Abstract
The invention comprises thiophosphoric acid esters of the formula:- <FORM:0877470/IV (b)/1> wherein Ar is phenyl, halogen-substituted phenyl, or C1-C4 alkyl-substituted phenyl radical, R1 and R2 are C1-C4 alkyl radicals, and X and Y are oxygen or sulphur with the proviso that when Y is sulphur X must also be sulphur. They may be obtained by reacting an appropriate O,O-dialkyl dithio- or monothio phosphoric acid with an appropriate aryl vinyl ether or thioether. The reaction may be carried out in an inert solvent, e.g. a hydrocarbon such as benzene or toluene and specified reaction temperatures are 50 - 70 DEG C. Examples are given for the production of compounds in which R1 and R2 are ethyl, X and Y are sulphur and Aryl is phenyl, p-chloro-phenyl, 3,4-dichlorophenyl, and p-methyl-phenyl respectively; R1 and R2 are ethyl, Y is oxygen, X is sulphur and Aryl is phenyl, p-chloro-phenyl, p-methyl-phenyl and 3,4-dimethyl phenyl respectively; R1 and R2 are methyl, X and Y are sulphur and aryl is phenyl, p-chlorophenyl, p-bromophenyl and p-methyl phenyl respectively. The products have insecticidal properties (see Group VI). Specification 676,776 is referred to.ALSO:An insecticidal composition comprises as active ingredient a thiophosphoric acid ester of the general formula <FORM:0877470/VI/1> in which Aryl is a phenyl, halogen-substituted phenyl, or C1-C4 alkyl substituted phenyl radical R1 and R2 are C1-C4 alkyl radicals , and X and Y are oxygen or sulphur with the proviso that when Y is sulphur X must also be sulphur (see Group IV (b)) and a solid or liquid carrier or diluent. Specified diluents are talcum, chalk, kieselguhr, organic solvents and water and the composition may be in the form of an aqueous emulsion obtained by using e.g. acetone or dimethyl formamide as dissolving agent, and a commercial emulsifier. Specified aryl radicals are phenyl, p-chlorophenyl, p-bromo-phenyl, p-methyl phenyl, 3,4-dichlorophenyl and 3,4-dimethyl-phenyl. Specification 676,776 is referred to.
