Abstract: Methods and intermediates useful for preparing a compound of formula I: and salts thereof.

Abstract: A method of preparing polymer, the method comprising polymerising one or more ethylenically unsaturated monomers of formula (I) where U is selected from H, C1-C4 alkyl or halogen; V is halogen or of the form O-G where G is selected from —C(O)R1 and —R1, or V is of the form NGGa where G is as defined above and Ga is selected from H and R1, G and Ga form together with N a heterocyclic ring, or V is of the form CH2Gb where Gb is selected from H, R1, OH, OR1, NR12, PR12, P(O)R12, P(OR1)2, SR1, SOR1, and SO2R1; and where the or each R1 is independently selected from optionally substituted alkyl, optionally substituted alkenyl, optionally substituted alkynyl, optionally substituted aryl, optionally substituted heteroaryl, optionally substituted carbocyclyl, optionally substituted heterocyclyl, optionally substituted arylalkyl, optionally substituted heteroarylalkyl, optionally substituted alkylaryl, optionally substituted alkylheteroaryl, and an optionally substituted polymer chain, under the control of a RA

Abstract: Carboxylate terminated thiocarbonates are reacted with a polyfunctional alcohol to form a hydroxyl-terminated thiocarbonate compound.

Abstract: This invention relates to novel alkylxanthates of formulae 1 to 3 and use of alkylxanthates of formulae 1 to 6 in the integrated pest management, more specifically alkyl xanthates are used as insect growth regulators for pest management in agricultural fields no or less environmental impact.

Abstract: Dye corresponding to the following formula - ##STR1## wherein Z represents CN, COOR.sup.1 or CONR.sup.2 R.sup.3 ;R.sup.1, R.sup.2 and R.sup.3 each independently represents hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted aryl, or R.sup.2 and R.sup.3 together represent the necessary atoms to close a heterocyclic nucleus or substituted heterocyclic nucleus;Y represents OR.sup.4 or NR.sup.5 R.sup.6 or CN;R.sup.4 represents hydrogen, substituted or unsubstituted or unsubstituted aryl, SO.sub.2 R.sup.7, COR.sup.7, CSR.sup.7, POR.sup.7 R.sup.8 ;R.sup.5 and R.sup.6 each independently has one of the significances given to R.sup.4 or represents substituted or unsubstituted amino, or R.sup.5 and R.sup.6 together represent the necessary atoms to close a heterocyclic nucleus or substituted heterocyclic nucleus, including a heterocyclic nucleus with an aliphatic or aromatic ring fused-on;R.sup.7 and R.sup.

Abstract: A methylene bisxanthate chemical compound is produced by reaction of an aqueous solution of an alkaline xanthate with methylene chloride in the presence of a polyethylene glycol (PEG) with alcoholic terminal groups as a phase transfer catalyst. The PEG is water soluble and may be recovered and recycled in the process. The reaction product may be purified, but can be used in the crude state as a collector reagent in the froth flotation of sulfide minerals, or of sulfidized oxide minerals, from their ores.

Abstract: Novel antitumor and antiviral xanthate compounds, a process for their production, pharmaceutical compositions containing said xanthate compounds, and a method of combating viruses and tumors therewith, are disclosed.

Abstract: Substituted phenoxy, phenylthio and anilino compounds, intermediates therefor, synthesis thereof, and their use for the control of pests.

Abstract: This invention relates to monoxanthates and dixanthates of dipropylene glycol and triethylene glycol. These xanthates increase both the rate of plant growth and the concentration of chlorophyll in the plants.

Abstract: Novel antiviral xanthate compounds, a process for their production, pharmaceutical compositions containing said xanthate compounds, and a method of combating viruses therewith, are disclosed.
