A variety of acetonitrile anion equivalents can be used in such reactions. Examples of such are tri-n-butylstannylacetonitrile, which can be coupled to compounds of formula (II) under Stifle reaction conditions as described by Mitiga et. al. (Chem. Left. 1984, 1511), or trimethylsilylacetonitrile in the presence of a palladium catalyst, such as tris(dibenzylideneacetone)dipalladium(0), and a ligand, for example Xantphos or P(t-Bu)3, a fluoride source, for example ZnF2, in an dipolar aprotic solvent such as DMF, at temperatures between 80-120° C. Such reactions are well precedented in the literature, for example see Hartwig et al. (J. Am. Chem. Soc. 2002, 124, 9330, and J. Am. Chem. Soc. 2005, 127, 15824).
Alternatively compounds of formula (III) can be prepared by a Suzuki reaction of a compound of formula (II) with a boronic acid of formula (IV):
In the presence of a base, such as potassium fluoride or cesium carbonate, a palladium catalysts, such as [1,1′-Bis (diphenylphosphino) ferrocene]dichloropalladium(II), and a polar aprotic solvent such as DMSO or DMF, at temperatures between 80-150° C. The reaction to compounds of formula (II) proceeds through an intermediate of formula (V)
The intermediate (V) can be converted directly to compounds of formula (III) in one pot, or isolated, and converted in a separate step to compounds of formula (III) by treatment with a suitable base, for example potassium fluoride or cesium carbonate. Such reactions are well known in the literature and have been described in J. Am. Chem. Soc. 2011, 133, 6948-6951.

Compounds of formula (Ia01) can be converted to compounds of formula (I) wherein R1 is C(O)R8, C(O)OR9, CONR10R11 by methods known to those skilled in the art, and illustrated in scheme 2.
In scheme 2, compounds of formula (Ia01) wherein R2, p, m, R3, R4, R5, R6, X, Y, Z, V, G1, and G2 are as described in formula (O) can be treated with a Grignard reagent of formula R8MgHal, followed by acidic hydrolysis (as described in C. Ferri, “Reaktionen der Organischen Synthese”, Georg Thieme Verlag, Stuttgart, 1978, page 324ff.) to give compounds of formula (Ia02), and wherein R8 is as defined in formula (I). Compounds of formula (Ia03) can be readily hydrolysed to the corresponding acid of formula (Ia04) by methods to known to those skilled in the art, for example by treatment with an alkaline base, for example lithium hydroxide, in water and a water miscible solvent, for example methanol or acetone. Compounds of (Ia04) can be activated to compounds of formula (Ia05), wherein (X03) is a leaving group such as halogen, or a mixed anhydride by methods known to those skilled in the art and described for example in Chem. Soc. Rev., 2009, 38, 606-631. Susbesquent treatment of compounds of formula (Ia05) with compounds of formula (VIIa) in the presence of a base, for example triethyl amine, and a catalyst, for example DMAP in an inert solvent, for example methylene chloride, leads to compounds of formula (Ia06).
Alternatively, compounds of formula (III) can be obtained from compounds of formula (II) by insertion of zinc into the C—X01 bond, for example by treatment with activated zinc metal in an an inert solvent, such as THF or diethyl ether, or by transmetllation of the corresponding lithium or magnesium reagents. The preparation of organo zinc reagents from halogens is well known to those skilled in the art and has been described in for example by Knochel et. al. in Chem. Rev. 1993, 93, 2117. Subsequent reaction of the organozinc reagent with a compound of formula (VII)
wherein X02 is halogen, preferably bromine, in the presence of a catalyst, for example Ni(acac)2, and a phosphine ligand, for example cyclohexyldiphenylphosphine, in an inert solvent such as tetrahydrofurane leads to compounds of formula (III). Such chemistry has been described in the literature (see Synthesis, 1987, 40-42). The compounds of formula (III) are converted to compounds of formula (I) as described in schemes 1 and 2.
Compounds of formula (I) wherein R1 is H can be prepared by direct Suzuki coupling of compounds of formula (II) with Boronic acids of formula (Villa) or Mollander salts of formula (VIIIb) by methods known to those skilled in the art, and described for example in Tetrahedron Letters, 43, 6987, 2002 or WO 2014/025736.
A further approach to compounds of formula (I) is illustrated in scheme 4.
As shown in scheme 4, compound of formula (II) is cross-coupled with a compound of formula (IX) in the presence of Ligand, e.g. Xant-Phos, a suitable palladium catalyst, e.g. Pd2(allyl)2Cl2, and a base e.g. DMAP inert solvent e.g. mesitylene as described in e.g. Y. S. Feng et al. Tetrahedron, 2012, 68, 2113, to give a compound of formula (X) wherein G1, G2, R3, R4, R5, R6, R9, m, V, X, Y and Z have the meanings described under formula I above. Compound (X) may be isolated or it can decarboxylate, spontaneously, or by heating in an inert solvent, such as DMSO to give a compound of formula (XI). Subsequent conversion to a compound of formula (Ia03) can be achieved as described previously and shown in scheme 4. Alternatively, compound of formula (II) can be decarboxylatively cross-coupled with a compound of formula (XII) under very similar conditions to give a compound of formula (III). Conversion of compounds of formula (III) to compounds of formula (Ia01) have been previously described (scheme 1).
The Palladium catalysed decarboxylative cross coupling has been described in analogous cases, e.g. in R. Shang et al. Angew. Chem. Int. Ed., 2011, 50, 4470.

Rev. 2000, 100, 3009-3066. The compounds of formula (XIII) obtained can be treated with compounds of formula (XIVa) or (XIVb) and a base, for example an alkaline metal hydride, for example sodium hydride, or an alkali metal alkoxide, for example potassium hydroxide, in an inert solvent such as DMF or toluene, to give compounds of formula (Ia07) wherein R1, X, Y, Z, G1, G2, V, R2, R4, R5, R6, R3 and m have the meanings as defined for formula (I).

Synthesis of the novel compounds of formula (IIb) wherein G2, R3, R4, R5, R6, m, V, X, and Y, have the definitions as previously described, and X01a, is halogen can be prepared by treatment of a compound of formula (XVI)
wherein Y, X, are as described in and X01a is halogen, with a compound of formula (XVII)
wherein X04 is halogen, and R4, R5, R6, R3 and m have the definitions described for formula (I), and R16a is hydrogen or C1-C4alkyl, in an inert solvent optionally in the presence of a suitable base in an inert solvent, to give compounds of formula (IIba).
wherein Y, X, X01a, V, R3, R4, R5 and R6 are as described in formula (I) and R16a is hydrogen or C1-C4alkyl.
Such reactions are well precedented in the literature (for example see WO 2013191113, or Archiv. Pharm. Res., 37(5), 588-599; 2014) and are usually carried out in an insert solvent such as ethanol or DMF at temperatures between 60-160° C., optionally in the presence of a base.
A further process to prepare compounds of formula (IIb), involves reacting a compound of formula (XIII) with a compound of (XVIII)
In the presence of a Lewis acid, such as Zinc(II)iodide or Indium(III) triflate, in an inert solvent such as chlorobenzene or 1,2,dichlorobenzene, with a catalytic copper(II) salt, such as Cu(II)acetate, under an oxygen or air atmosphere at temperatures between 100-180° C., preferably 110-140° C., to give compounds of formula (IIba) wherein R16a is hydrogen. Such reactions have previously been described in the literature (see Adv. Synth. Catal. 2013, 355, 1741-1747, and J. Org. Chem., 2013, 78, 12494-12504, when R16a is hydrogen). Compounds of formula (XVII) and (XVIII) can be prepared from compounds of formula (XIX) by, for example, the methods shown in scheme 6.
In scheme 6, an acyl halide of formula (XIXa) is converted to a Weinreb amide (XX) upon reaction with N,O-Dimethylhydroxylamine by methods known to those skilled in the art and described for example in C. Ferri, “Reaktionen der Organischen Synthese”, Georg Thieme Verlag, Stuttgart, 1978, page 223ff. the Weinreb amide of formula (XX) is then reacted with a Grignard reagent of formula R16aCH2MgHal (XXI) according to the method of Weinreb (Tetrahedron Letters 1981, 22, 3815-3818) to give compounds of formula XXVII and XXVIIa. Compounds of formula XXVII and XXVIIa can also be prepared by treatment of nitrile compounds of formula XXII, with a Grignard reagent of formula R16aCH2MgHal, followed by acidic hydrolysis (as described in C. Ferri, “Reaktionen der Organischen Synthese”, Georg Thieme Verlag, Stuttgart, 1978, page 223ff.).
Compounds of formula XXVII and XXVIIl can be halogenated to compounds of formula XVII, with for example mixtures of bromine and hydrobromic acid in acetic acid (as described in Phosphorus, Sulfur and Silicon and the Related Elements, 2013, 188(12), 1835-1844) or with, for example, copper(II)bromide in an inert solvent, for example chloroform, ethyl acetate and the like, as described in J. Med. Chem., 2013, 56(1), 84-96. Alternatively compounds of formula XVII where R16a is hydrogen, can be prepared directly from compounds of formula XIXa by treatment with diazomethane or trimethyl silyl diazomethane and subsequent treatment with an halogen acid, for example, hydrobromic acid or hydrochloric acid in an inert solvent such as diethyl ether. Such procedures are well known in the literature, for example see Eu. J. Med. Chem., 1987, 22(5), 457-62 and WO 2009010455.
Compounds of the formula XVI are generally known in the literature, for example (CAS index numbers in brackets); 4-bromopyridin-2-amine [84249-14-9], 5-bromopyridazin-3-amine [1187237-00-8] and 6-bromopyrimidin-4-amine [1159818-57-1]. Compounds of formula (XIX) used in this invention are generally known and have been described in WO12/086848, WO13/018928, WO12/086848, WO 2013/187422, WO 2013/191113, and WO 2013/191188.
Compounds of formula (IIc)
can be prepared for example as shown in scheme 7 for the representative example compound of formula (IIca01):
Intermediates of formula (III),
wherein G1, G2, R3, R4, R5, R6, m, V, X, Z and Y have the definitions as described under formula (I) above are novel and were developed specifically for the preparation of the compounds of the formula (I). Accordingly, they also form part of the subject-matter of the present invention. The preferred substituent definitions for formula I, Ia, Ib, Ic and Id mentioned above are also valid for the preferred compounds of formula III.
The reactants can be reacted in the presence of a base. Examples of suitable bases are alkali metal or alkaline earth metal hydroxides, alkali metal or alkaline earth metal hydrides, alkali metal or alkaline earth metal amides, alkali metal or alkaline earth metal alkoxides, alkali metal or alkaline earth metal acetates, alkali metal or alkaline earth metal carbonates, alkali metal or alkaline earth metal dialkylamides or alkali metal or alkaline earth metal alkylsilylamides, alkylamines, alkylenediamines, free or N-alkylated saturated or unsaturated cycloalkylamines, basic heterocycles, ammonium hydroxides and carbocyclic amines. Examples which may be mentioned are sodium hydroxide, sodium hydride, sodium amide, sodium methoxide, sodium acetate, sodium carbonate, potassium tert-butoxide, potassium hydroxide, potassium carbonate, potassium hydride, lithium diisopropylamide, potassium bis(trimethylsilyl)amide, calcium hydride, triethylamine, diisopropylethylamine, triethylenediamine, cyclohexylamine, N-cyclohexyl-N,N-dimethylamine, N,N-diethylaniline, pyridine, 4-(N,N-dimethylamino)pyridine, quinuclidine, N-methylmorpholine, benzyltrimethylammonium hydroxide and 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU).
The reactants can be reacted with each other as such, i.e. without adding a solvent or diluent In most cases, however, it is advantageous to add an inert solvent or diluent or a mixture of these. If the reaction is carried out in the presence of a base, bases which are employed in excess, such as triethylamine, pyridine, N-methylmorpholine or N,N-diethylaniline, may also act as solvents or diluents.
The reaction is advantageously carried out in a temperature range from approximately −80° C. to approximately +140° C., preferably from approximately −30° C. to approximately +100° C., in many cases in the range between ambient temperature and approximately +80° C.
A compound of formula (I) can be converted in a manner known per se into another compound of formula (I) by replacing one or more substituents of the starting compound of formula (I) in the customary manner by (an)other substituent(s) according to the invention.
Depending on the choice of the reaction conditions and starting materials which are suitable in each case, it is possible, for example, in one reaction step only to replace one substituent by another substituent according to the invention, or a plurality of substituents can be replaced by other substituents according to the invention in the same reaction step.
Salts of compounds of formula (I) can be prepared in a manner known per se. Thus, for example, acid addition salts of compounds of formula (I) are obtained by treatment with a suitable acid or a suitable ion exchanger reagent and salts with bases are obtained by treatment with a suitable base or with a suitable ion exchanger reagent.
Salts of compounds of formula (I) can be converted in the customary manner into the free compounds (I), acid addition salts, for example, by treatment with a suitable basic compound or with a suitable ion exchanger reagent and salts with bases, for example, by treatment with a suitable acid or with a suitable ion exchanger reagent.
Salts of compounds of formula (I) can be converted in a manner known per se into other salts of compounds of formula (I) I, acid addition salts, for example, into other acid addition salts, for example by treatment of a salt of inorganic acid such as hydrochloride with a suitable metal salt such as a sodium, barium or silver salt, of an acid, for example with silver acetate, in a suitable solvent in which an inorganic salt which forms, for example silver chloride, is insoluble and thus precipitates from the reaction mixture.
Depending on the procedure or the reaction conditions, the compounds of formula (I), which have salt-forming properties can be obtained in free form or in the form of salts.
The compounds of formula (I) and, where appropriate, the tautomers thereof, in each case in free form or in salt form, can be present in the form of one of the isomers which are possible or as a mixture of these, for example in the form of pure isomers, such as antipodes and/or diastereomers, or as isomer mixtures, such as enantiomer mixtures, for example racemates, diastereomer mixtures or racemate mixtures, depending on the number, absolute and relative configuration of asymmetric carbon atoms which occur in the molecule and/or depending on the configuration of non-aromatic double bonds which occur in the molecule; the invention relates to the pure isomers and also to all isomer mixtures which are possible and is to be understood in each case in this sense hereinabove and hereinbelow, even when stereochemical details are not mentioned specifically in each case.
Diastereomer mixtures or racemate mixtures of compounds of formula (I), in free form or in salt form, which can be obtained depending on which starting materials and procedures have been chosen can be separated in a known manner into the pure diasteromers or racemates on the basis of the physicochemical differences of the components, for example by fractional crystallization, distillation and/or chromatography.
Enantiomer mixtures, such as racemates, which can be obtained in a similar manner can be resolved into the optical antipodes by known methods, for example by recrystallization from an optically active solvent, by chromatography on chiral adsorbents, for example high-performance liquid chromatography (HPLC) on acetyl cellulose, with the aid of suitable microorganisms, by cleavage with specific, immobilized enzymes, via the formation of inclusion compounds, for example using chiral crown ethers, where only one enantiomer is complexed, or by conversion into diastereomeric salts, for example by reacting a basic end-product racemate with an optically active acid, such as a carboxylic acid, for example camphor, tartaric or malic acid, or sulphonic acid, for example camphorsulphonic acid, and separating the diastereomer mixture which can be obtained in this manner, for example by fractional crystallization based on their differing solubilities, to give the diastereomers, from which the desired enantiomer can be set free by the action of suitable agents, for example basic agents.
Pure diastereomers or enantiomers can be obtained according to the invention not only by separating suitable isomer mixtures, but also by generally known methods of diastereoselective or enantioselective synthesis, for example by carrying out the process according to the invention with starting materials of a suitable stereochemistry.
N-oxides can be prepared by reacting a compound of the formula (I) with a suitable oxidizing agent, for example the H2O2/urea adduct in the presence of an acid anhydride, e.g. trifluoroacetic anhydride. Such oxidations are known from the literature, for example from J. Med. Chem., 32 (12), 2561-73, 1989 or WO 00/15615.
It is advantageous to isolate or synthesize in each case the biologically more effective isomer, for example enantiomer or diastereomer, or isomer mixture, for example enantiomer mixture or diastereomer mixture, if the individual components have a different biological activity.
The compounds of formula (I) and, where appropriate, the tautomers thereof, in each case in free form or in salt form, can. If appropriate, also be obtained in the form of hydrates and/or include other solvents, for example those which may have been used for the crystallization of compounds which are present in solid form.

Toxins that can be expressed by such transgenic plants include, for example, insecticidal proteins, for example insecticidal proteins from Bacillus cereus or Bacillus poplliae; or insecticidal proteins from Bacillus thuringiensis, such as δ-endotoxins, e.g. Cry1Ab, Cry1Ac, Cry1F, Cry1Fa2, Cry2Ab. Cry3A, Cry3Bb1 or Cry9C, or vegetative insecticidal proteins (Vip), e.g. Vip1, Vip2, Vip3 or Vip3A; or insecticidal proteins of bacteria colonising nematodes, for example Photorhabdus spp. or Xenorhabdus spp., such as Photorhabdus luminescens, Xenorhabdus nematophilus; toxins produced by animals, such as scorpion toxins, arachnid toxins, wasp toxins and other insect-specific neurotoxins; toxins produced by fungi, such as Streptomycetes toxins, plant lectins. such as pea lectins, barley lectins or snowdrop lectins; agglutinins; proteinase inhibitors, such as trypsin inhibitors, serine protease inhibitors, patatin, cystatin, papain inhibitors; ribosome-inactivating proteins (RIP), such as ricin, maize-RIP, abrin, luffin, saporin or bryodin; steroid metabolism enzymes, such as 3-hydroxysteroidoxidase, ecdysteroid-UDP-glycosyl-transferase, cholesterol oxidases, ecdysone inhibitors, HMG-COA-reductase, ion channel blockers, such as blockers of sodium or calcium channels, juvenile hormone esterase, diuretic hormone receptors, stilbene synthase, bibenzyl synthase, chitinases and glucanases.
In the context of the present invention there are to be understood by δ-endotoxins, for example Cry1Ab, Cry1Ac. Cry1F, Cry1 Fa2, Cry2Ab, Cry3A, Cry3Bb1 or Cry9C, or vegetative insecticidal proteins (Vip), for example Vip1, Vip2, Vip3 or Vip3A, expressly also hybrid toxins, truncated toxins and modified toxins.
Hybrid toxins are produced recombinantly by a new combination of different domains of those proteins (see, for example, WO 02/15701). Truncated toxins, for example a truncated Cry1Ab, are known. In the case of modified toxins, one or more amino acids of the naturally occurring toxin are replaced. In such amino acid replacements, preferably non-naturally present protease recognition sequences are inserted into the toxin, such as, for example, in the case of Cry3A055, a cathepsin-G-recognition sequence is inserted into a Cry3A toxin (see WO 03/018810).
Examples of such toxins or transgenic plants capable of synthesising such toxins are disclosed, for example, in EP-A-0 374 753. WO 93/07278, WO 95/34656, EP-A-0 427 529, EP-A-451 878 and WO 03/052073.
The processes for the preparation of such transgenic plants are generally known to the person skilled in the art and are described, for example, in the publications mentioned above. CryI-type deoxyribonucleic acids and their preparation are known, for example, from WO 95/34656, EP-A-0 367 474, EP-A-0 401 979 and WO 90/13651.
The toxin contained in the transgenic plants imparts to the plants tolerance to harmful insects. Such insects can occur in any taxonomic group of insects, but are especially commonly found in the beetles (Coleoptera), two-winged insects (Diptera) and moths (Lepidoptera).
Transgenic plants containing one or more genes that code for an insecticidal resistance and express one or more toxins are known and some of them are commercially available. Examples of such plants are: YieldGard® (maize variety that expresses a Cry1Ab toxin); YieldGard Rootworm® (maize variety that expresses a Cry3Bb1 toxin); YieldGard Plus® (maize variety that expresses a Cry1 Ab and a Cry3Bb1 toxin); Starlink® (maize variety that expresses a Cry9C toxin); Herculex I® (maize variety that expresses a Cry1 Fa2 toxin and the enzyme phosphinothricine N-acetyltransferase (PAT) to achieve tolerance to the herbicide glufosinate ammonium); NuCOTN 33B® (cotton variety that expresses a Cry1Ac toxin); Bollgard I® (cotton variety that expresses a Cry1Ac toxin); Bollgard II® (cotton variety that expresses a Cry1Ac and a Cry2Ab toxin); VipCot® (cotton variety that expresses a Vi3A and a Cry1Ab toxin); NewLeaf® (potato variety that expresses a Cry3A toxin); NatureGard®, Agrisure® GT Advantage (GA21 glyphosate-tolerant trait). Agrisure® CB Advantage (Bt11 corn borer (CB) trait) and Protecta®.

Transgenic crops of insect-resistant plants are also described in BATS (Zentrum für Biosicherheit und Nachhaltigkeit, Zentrum BATS, Clarastrasse 13, 4058 Basel, Switzerland) Report 2003, (http://bats.ch). The term “crops” is to be understood as including also crop plants which have been so transformed by the use of recombinant DNA techniques that they are capable of synthesising antipathogenic substances having a selective action, such as, for example, the so-called “pathogenesis-related proteins” (PRPs, see e.g. EP-A-0 392 225). Examples of such antipathogenic substances and transgenic plants capable of synthesising such antipathogenic substances are known, for example, from EP-A-0 392 225, WO 95/33818 and EP-A-0 353 191. The methods of producing such transgenic plants are generally known to the person skilled in the art and are described, for example, in the publications mentioned above.
Crops may also be modified for enhanced resistance to fungal (for example Fusarium, Anthracnose, or Phytophthora), bacterial (for example Pseudomonas) or viral (for example potato leafroll virus, tomato spotted wilt virus, cucumber mosaic virus) pathogens.
Crops also include those that have enhanced resistance to nematodes, such as the soybean cyst nematode.
Crops that are tolerance to abiotic stress include those that have enhanced tolerance to drought, high salt, high temperature, chill, frost, or light radiation, for example through expression of NF—YB or other proteins known in the art.
Antipathogenic substances which can be expressed by such transgenic plants include, for example, ion channel blockers, such as blockers for sodium and calcium channels, for example the viral KP1, KP4 or KP6 toxins; stilbene synthases; bibenzyl synthases; chitinases; glucanases: the so-called “pathogenesis-related proteins” (PRPs; see e.g. EP-A-0 392 225); antipathogenic substances produced by microorganisms, for example peptide antibiotics or heterocyclic antibiotics (see e.g. WO 95/33818) or protein or polypeptide factors involved in plant pathogen defence (so-called “plant disease resistance genes”, as described in WO 03/000906).
Further areas of use of the compositions according to the invention are the protection of stored goods and store ambients and the protection of raw materials, such as wood, textiles, floor coverings or buildings, and also in the hygiene sector, especially the protection of humans, domestic animals and productive livestock against pests of the mentioned type.
The present invention also provides a method for controlling pests (such as mosquitoes and other disease vectors; see also http://www.who.int/malaria/vector_control/irs/en/). In one embodiment, the method for controlling pests comprises applying the compositions of the invention to the target pests, to their locus or to a surface or substrate by brushing, rolling, spraying, spreading or dipping. By way of example, an IRS (indoor residual spraying) application of a surface such as a wall, ceiling or floor surface is contemplated by the method of the invention. In another embodiment, it is contemplated to apply such compositions to a substrate such as non-woven or a fabric material in the form of (or which can be used in the manufacture of) netting, clothing, bedding, curtains and tents.

The polyesters are particularly suitable. The methods of textile treatment are known, e.g. WO 2008/151984, WO 2003/034823, U.S. Pat. No. 5,631,072, WO 2005/064072, WO 2006/128870, EP 1724392, WO 2005/113886 or WO 2007/090739.

The invention therefore also relates to pesticidal compositions such as emulsifiable concentrates, suspension concentrates, microemulsions, oil dispersibles, directly sprayable or dilutable solutions, spreadable pastes, dilute emulsions, soluble powders, dispersible powders, wettable powders, dusts, granules or encapsulations in polymeric substances, which comprise—at least—one of the active ingredients according to the invention and which are to be selected to suit the intended aims and the prevailing circumstances.
In these compositions, the active ingredient is employed in pure form, a solid active ingredient for example in a specific particle size, or, preferably, together with—at least—one of the auxiliaries conventionally used in the art of formulation, such as extenders, for example solvents or solid carriers, or such as surface-active compounds (surfactants).
Examples of suitable solvents are: unhydrogenated or partially hydrogenated aromatic hydrocarbons, preferably the fractions C8 to C12 of alkylbenzenes, such as xylene mixtures, alkylated naphthalenes or tetrahydronaphthalene, aliphatic or cycloaliphatic hydrocarbons, such as paraffins or cyclohexane, alcohols such as ethanol, propanol or butanol, glycols and their ethers and esters such as propylene glycol, dipropylene glycol ether, ethylene glycol or ethylene glycol monomethyl ether or ethylene glycol monoethyl ether, ketones, such as cyclohexanone, isophorone or diacetone alcohol, strongly polar solvents, such as N-methylpyrrolid-2-one, dimethyl sulfoxide or N,N-dimethylformamide, water, unepoxidized or epoxidized vegetable oils, such as unexpodized or epoxidized rapeseed, castor, coconut or soya oil, and silicone oils.
Solid carriers which are used for example for dusts and dispersible powders are, as a rule, ground natural minerals such as calcite, talc, kaolin, montmorillonite or attapulgite. To improve the physical properties, it is also possible to add highly disperse silicas or highly disperse absorbtive polymers. Suitable adsorptive carriers for granules are porous types, such as pumice, brick grit, sepiolite or bentonite, and suitable non-sorptive carrier materials are calcite or sand. In addition, a large number of granulated materials of inorganic or organic nature can be used, in particular dolomite or comminuted plant residues.
Suitable surface-active compounds are, depending on the type of the active ingredient to be formulated, non-ionic, cationic and/or anionic surfactants or surfactant mixtures which have good emulsifying, dispersing and wetting properties. The surfactants mentioned below are only to be considered as examples; a large number of further surfactants which are conventionally used in the art of formulation and suitable according to the invention are described in the relevant literature.
Suitable non-ionic surfactants are, especially, polyglycol ether derivatives of aliphatic or cycloaliphatic alcohols, of saturated or unsaturated fatty acids or of alkyl phenols which may contain approximately 3 to approximately 30 glycol ether groups and approximately 8 to approximately 20 carbon atoms in the (cyclo)aliphatic hydrocarbon radical or approximately 6 to approximately 18 carbon atoms in the alkyl moiety of the alkyl phenols. Also suitable are water-soluble polyethylene oxide adducts with polypropylene glycol, ethylenediaminopolypropylene glycol or alkyl polypropylene glycol having 1 to approximately 10 carbon atoms in the alkyl chain and approximately 20 to approximately 250 ethylene glycol ether groups and approximately 10 to approximately 100 propylene glycol ether groups. Normally, the abovementioned compounds contain 1 to approximately 5 ethylene glycol units per propylene glycol unit. Examples which may be mentioned are nonylphenoxypolyethoxyethanol, castor oil polyglycol ether, polypropylene glycol/polyethylene oxide adducts, tributylphenoxypolyethoxyethanol, polyethylene glycol or octylphenoxypolyethoxyethanol. Also suitable are fatty acid esters of polyoxyethylene sorbitan, such as polyoxyethylene sorbitan trioleate.
The cationic surfactants are, especially, quarternary ammonium salts which generally have at least one alkyl radical of approximately 8 to approximately 22 C atoms as substituents and as further substituents (unhalogenated or halogenated) lower alkyl or hydroxyalkyl or benzyl radicals. The salts are preferably in the form of halides, methylsulfates or ethylsulfates. Examples are stearyltrimethylammonium chloride and benzylbis(2-chloroethyl)ethylammonium bromide.
Examples of suitable anionic surfactants are water-soluble soaps or water-soluble synthetic surface-active compounds. Examples of suitable soaps are the alkali, alkaline earth or (unsubstituted or substituted) ammonium salts of fatty acids having approximately 10 to approximately 22 C atoms, such as the sodium or potassium salts of oleic or stearic acid, or of natural fatty acid mixtures which are obtainable for example from coconut or tall oil; mention must also be made of the fatty acid methyl taurates. However, synthetic surfactants are used more frequently, in particular fatty sulfonates, fatty sulfates, sulfonated benzimidazole derivatives or alkylaryl sulfonates. As a rule, the fatty sulfonates and fatty sulfates are present as alkali, alkaline earth or (substituted or unsubstituted) ammonium salts and they generally have an alkyl radical of approximately 8 to approximately 22 C atoms, alkyl also to be understood as including the alkyl moiety of acyl radicals; examples which may be mentioned are the sodium or calcium salts of lignosulfonic acid, of the dodecylsulfuric ester or of a fatty alcohol sulfate mixture prepared from natural fatty acids. This group also includes the salts of the sulfuric esters and sulfonic acids of fatty alcohol/ethylene oxide adducts. The sulfonated benzimidazole derivatives preferably contain 2 sulfonyl groups and a fatty acid radical of approximately 8 to approximately 22 C atoms. Examples of alkylarylsulfonates are the sodium, calcium or triethanolammonium salts of decylbenzenesulfonic acid, of dibutylnaphthalenesulfonic acid or of a naphthalenesulfonic acid/formaldehyde condensate. Also possible are, furthermore, suitable phosphates, such as salts of the phosphoric ester of a p-nonylphenol/(4-14)ethylene oxide adduct, or phospholipids.
As a rule, the compositions comprise 0.1 to 99%, especially 0.1 to 95%, of active ingredient and 1 to 99.9%, especially 5 to 99.9%, of at least one solid or liquid adjuvant, it being possible as a rule for 0 to 25%, especially 0.1 to 20%, of the composition to be surfactants (% in each case meaning percent by weight). Whereas concentrated compositions tend to be preferred for commercial goods, the end consumer as a rule uses dilute compositions which have substantially lower concentrations of active ingredient.
Typically, a pre-mix formulation for foliar application comprises 0.1 to 99.9%, especially 1 to 95%, of the desired ingredients, and 99.9 to 0.1%, especially 99 to 5%, of a solid or liquid adjuvant (including, for example, a solvent such as water), where the auxiliaries can be a surfactant in an amount of 0 to 50%, especially 0.5 to 40%, based on the pre-mix formulation.
Normally, a tank-mix formulation for seed treatment application comprises 0.25 to 80%, especially 1 to 75%, of the desired ingredients, and 99.75 to 20%, especially 99 to 25%, of a solid or liquid auxiliaries (including, for example, a solvent such as water), where the auxiliaries can be a surfactant in an amount of 0 to 40%, especially 0.5 to 30%, based on the tank-mix formulation.
Typically, a pre-mix formulation for seed treatment application comprises 0.5 to 99.9%, especially 1 to 95%, of the desired ingredients, and 99.5 to 0.1%, especially 99 to 5%, of a solid or liquid adjuvant (including, for example, a solvent such as water), where the auxiliaries can be a surfactant in an amount of 0 to 50%, especially 0.5 to 40%, based on the pre-mix formulation.
Whereas commercial products will preferably be formulated as concentrates (e.g., pre-mix composition (formulation)), the end user will normally employ dilute formulations (e.g., tank mix composition).
Preferred seed treatment pre-mix formulations are aqueous suspension concentrates. The formulation can be applied to the seeds using conventional treating techniques and machines, such as fluidized bed techniques, the roller mil method, rotostatic seed treaters, and drum coaters. Other methods, such as spouted beds may also be useful. The seeds may be presized before coating. After coating, the seeds are typically dried and then transferred to a sizing machine for sizing. Such procedures are known in the art.
In general, the pre-mix compositions of the invention contain 0.5 to 99.9 especially 1 to 95, advantageously 1 to 50%, by mass of the desired ingredients, and 99.5 to 0.1, especially 99 to 5%, by mass of a solid or liquid adjuvant (including, for example, a solvent such as water), where the auxiliaries (or adjuvant) can be a surfactant in an amount of 0 to 50, especially 0.5 to 40%, by mass based on the mass of the pre-mix formulation.

The active ingredient mixture of the compounds of formula I selected from Table Table 1 to 11 and A with active ingredients described above comprises a compound selected from Table Table 1 to 11 and A and an active ingredient as described above preferably in a mixing ratio of from 100:1 to 1:6000, especially from 50:1 to 1:50, more especially in a ratio of from 20:1 to 1:20, even more especially from 10:1 to 1:10, very especially from 5:1 and 1:5, special preference being given to a ratio of from 2:1 to 1:2, and a ratio of from 4:1 to 2:1 being likewise preferred, above all in a ratio of 1:1, or 5:1, or 5:2, or 5:3, or 5:4, or 4:1, or 4:2, or 4:3, or 3:1, or 3:2, or 2:1, or 1:5, or 2:5, or 3:5, or 4:5, or 1:4, or 2:4, or 3:4, or 1:3, or 2:3, or 1:2, or 1:600, or 1:300, or 1:150, or 1:35, or 2:35, or 4:35, or 1:75, or 2:75, or 4:75, or 1:6000, or 1:3000, or 1:1500, or 1:350, or 2:350, or 4:350, or 1:750, or 2:750, or 4:750. Those mixing ratios are by weight.
The mixtures as described above can be used in a method for controlling pests, which comprises applying a composition comprising a mixture as described above to the pests or their environment, with the exception of a method for treatment of the human or animal body by surgery or therapy and diagnostic methods practised on the human or animal body.
The mixtures comprising a compound of formula I selected from Table Table 1 to 11 and A and one or more active ingredients as described above can be applied, for example, in a single “ready-mix” form, in a combined spray mixture composed from separate formulations of the single active ingredient components, such as a “tank-mix”, and in a combined use of the single active ingredients when applied in a sequential manner, i.e. one after the other with a reasonably short period, such as a few hours or days. The order of applying the compounds of formula I selected from Table Table 1 to 11 and A and the active ingredients as described above is not essential for working the present invention.
The compositions according to the invention can also comprise further solid or liquid auxiliaries, such as stabilizers, for example unepoxidized or epoxidized vegetable oils (for example epoxidized coconut ol, rapeseed oil or soya oil), antifoams, for example silicone oil, preservatives, viscosity regulators, binders and/or tackifers, fertilizers or other active ingredients for achieving specific effects, for example bactericides, fungicides, nematocides, plant activators, molluscicides or herbicides.
The compositions according to the invention are prepared in a manner known per se, in the absence of auxiliaries for example by grinding, screening and/or compressing a solid active ingredient and in the presence of at least one auxiliary for example by intimately mixing and/or grinding the active ingredient with the auxiliary (auxiliaries). These processes for the preparation of the compositions and the use of the compounds I for the preparation of these compositions are also a subject of the invention.
The application methods for the compositions, that is the methods of controlling pests of the abovementioned type, such as spraying, atomizing, dusting, brushing on, dressing, scattering or pouring—which are to be selected to suit the intended aims of the prevailing circumstances—and the use of the compositions for controlling pests of the abovementioned type are other subjects of the invention. Typical rates of concentration are between 0.1 and 1000 ppm, preferably between 0.1 and 500 ppm, of active ingredient. The rate of application per hectare is generally 1 to 2000 g of active ingredient per hectare, in particular 10 to 1000 g/ha, preferably 10 to 600 g/ha.
A preferred method of application in the field of crop protection is application to the foliage of the plants (foliar application), it being possible to select frequency and rate of application to match the danger of infestation with the pest in question. Alternatively, the active ingredient can reach the plants via the root system (systemic action), by drenching the locus of the plants with a liquid composition or by incorporating the active ingredient in solid form into the locus of the plants, for example into the soil, for example in the form of granules (sol application). In the case of paddy rice crops, such granules can be metered into the flooded paddy-field.
The compounds of the invention and compositions thereof are also be suitable for the protection of plant propagation material, for example seeds, such as fruit, tubers or kernels, or nursery plants, against pests of the abovementioned type. The propagation material can be treated with the compound prior to planting, for example seed can be treated prior to sowing. Alternatively, the compound can be applied to seed kernels (coating), either by soaking the kernels in a liquid composition or by applying a layer of a solid composition. It is also possible to apply the compositions when the propagation material is planted to the site of application, for example into the seed furrow during drilling. These treatment methods for plant propagation material and the plant propagation material thus treated are further subjects of the invention. Typical treatment rates would depend on the plant and pest/fungi to be controlled and are generally between 1 to 200 grams per 100 kg of seeds, preferably between 5 to 150 grams per 100 kg of seeds, such as between 10 to 100 grams per 100 kg of seeds.
The term seed embraces seeds and plant propagules of all kinds including but not limited to true seeds, seed pieces, suckers, cons, bulbs, fruit, tubers, grains, rhizomes, cuttings, cut shoots and the like and means in a preferred embodiment true seeds.
The present invention also comprises seeds coated or treated with or containing a compound of formula I. The term “coated or treated with and/or containing” generally signifies that the active ingredient is for the most part on the surface of the seed at the time of application, although a greater or lesser part of the ingredient may penetrate into the seed material, depending on the method of application. When the said seed product is (re)planted, it may absorb the active ingredient. In an embodiment, the present invention makes available a plant propagation material adhered thereto with a compound of formula (I). Further, it is hereby made available, a composition comprising a plant propagation material treated with a compound of formula (I).
Seed treatment comprises all suitable seed treatment techniques known in the art, such as seed dressing, seed coating, seed dusting, seed soaking and seed pelleting. The seed treatment application of the compound formula (I) can be carried out by any known methods, such as spraying or by dusting the seeds before sowing or during the sowing/planting of the seeds.
