Abstract: This invention relates to the stoichiometric condensation of substituted phenylacetonitriles with dibasic carboxylic anhydrides. The resulting cyano-keto-acids are obtained in good yield and can be used to prepare biologically active 2-aryl-1,3-cyclohexanediones without elaborate purification.

Abstract: This invention relates to the stoichiometric condensation of substituted phenylacetonitriles with mono-esters of dibasic carboxylic acids. Use of the mono-ester results in substantially purer product by eliminating the bis-condensation observed with use of the diester reactant. The resulting cyano-keto-acids are obtained in good yield and can be used to prepare biologically active 2-aryl-1,3-cyclohexanediones without elaborate purification.

Abstract: Novel cyano enol phosphates are provided which have utility as pesticides.

Abstract: A novel process is provided for the preparation of carbofuran and certain intermediate products. 1,2-Cyclohexanedione is alkylated with a beta-methallyl compound and the resulting product subjected to a Claisen rearrangement/aromatization to provide the carbofuran phenol. Reaction of the phenol with methyl isocyanate converts the phenol to the desired carbofuran.

Abstract: This invention relates to compositions and the synthesis thereof of novel phosphorous esters of bisphenols which are effective broad spectrum acaricides and insecticides.

Abstract: Esters of 3,5-dibromo-4-hydroxybenzonitrile can be prepared in high yields from 4-cyanophenol in a single solvent. In this manner, the 3,5-dibromo-4-hydroxybenzonitrile intermediate need not be isolated, and therefore the bromination and esterification reactions can be performed in one reactor. Preferably, the bromination is accomplished with bromine chloride in the presence of 1,1,2-trichloroethane followed by esterification with an acid chloride in the same solvent.

Abstract: This invention relates to chewing insect toxicant compositions comprising (1) a 1-(mono-substituted phenyl)-3-benzoyl urea compound in admixture with (2) an amount sufficient to enhance the chewing insect toxicity of said urea compound of a phosphorous-containing compound. This invention is also directed to chewing insect toxicant compositions comprising an acceptable carrier and as the active toxicant an effective amount of the composition of this invention as well as to a method of controlling insects by subjecting them to an effective amount of the composition of this invention.

Abstract: Novel phosphorous esters of substituted phenols have been found to exhibit insecticidal and miticidal activity.

Abstract: Esters of 3,5-dibromo-4-hydroxybenzonitrile can be prepared in high yields from 4-cyanophenol by reacting said phenol with preformed bromine chloride in 3% aqueous hydrogen bromide and then azeotropically distilling off the solvent/reaction medium with an aromatic hydrocarbon which then serves as the esterifying solvent medium for reaction with an acid halide. In this manner, both reactions can be accomplished without removing the product of the bromination reaction from the reaction vessel, i.e., a solids separation step is avoided.

Abstract: This invention relates to novel esters of benzofuranyl acids, novel intermediates therefor, synthesis thereof, and the control of pests.

Abstract: Novel bicyclooxyphenyl ureas, such as 1-(bicyclooxyphenyl)-benzoyl ureas, are provided which exhibit pesticidal activity. The compositions are conveniently prepared by reacting an isocyanate with either an amide or a bicyclooxyaniline.

Abstract: Novel 2,6-dihalogenated benzylidene aminooxyacetic acid compounds and derivatives thereof, have been found to have exceptional herbicidal activity, particularly in regard to nutsedge control.

Abstract: This invention relates to novel ester compounds derived from alkynoic acids and to their preparation. This invention is also directed to insecticidal and miticidal compositions comprising an acceptable carrier and an insecticidally or miticidally effective amount of a novel ester compound of this invention as well as a method of controlling pests by subjecting them to an insecticidally or miticidally effective amount of a novel ester compound of this invention.

Abstract: 2-Aryl-1, 3-cyclohexanedione enol ester compounds exhibit outstanding miticidal,mite ovicidal and herbicidal activity.

Abstract: This invention relates to novel hydroxyarylalkyleneaminoaryl carbamate compounds and derivatives thereof and to their preparation. This invention is also directed to insecticidal compositions comprising an acceptable carrier and an insecticidally effective amount of a hydroxyarylalkyleneaminoaryl carbamate compound or derivative of this invention as well as to a method of controlling insects by subjecting them to an insecticidally effective amount of a hydroxyarylalkyleneaminoaryl carbamate compound or derivative of this invention.

Abstract: An improved process for preparing 1-organothioaldoxime compounds by reacting an aldoxime or .alpha.-hydroxyiminoketone with an alkaline hypohalite in an acidic medium and reacting the resulting 1-haloaldoxime with the alkali metal salt of a mercaptan, said acidic medium comprising an acid added in an amount of from about 0.5 to about 4.0 equivalents for each mole of alkaline hypohalite used.

Abstract: A rotary ball valve comprises a housing formed of plastic material, the housing including a through passage. A plug formed of a plastic material is rotatably mounted in the housing and includes a ball-shaped gate having a passage which is alignable with the housing passage when the plug is open. A stem projects laterally of the housing passage to enable the plug to be manually rotated. A pair of seating rings formed of an anti-friction material encircle respective ends of the gate passage when the plug is open. The housing includes a pair of annular flanges disposed on opposite sides of the plug passage. Each flange contacts a back side of a respective one of the seating rings. Each flange is notched around its periphery to form a plurality of circumferentially spaced flange segments whose inner diameter is substantially the same as the diameter of the gate passage.
