Abstract:
Compounds and compositions containing them, for insecticidal control, particularly for use as soil and/or foliar insecticides, have the formula in which R 1 is C 1 -C 3 alkyl; R 2 is C 1 -C 6 alkyl or C 5 -C 6 cycloalkyl; R 3 is hydrogen or C 1 -C 3 alkyl; R 4 is hydrogen, C 1 -C 4 alkyl, phenyl, halogen or halo-(C 1 -C 4 alkyl); and R 5 and R 6 are independently hydrogen, halogen, C 1 -C 4 alkyl, phenyl, or C 2 -C 5 carboalkoxy; or R 3 and R 5 taken together form a trimethylene group; provided that if R 3 , R 5 and R 6 are all hydrogen, R 4 is not hydrogen; together with insecticidal compositions containing such compounds, and methods for controlling insects.

Abstract:
Compounds having the formula in which R, is C 1 -C 3 alkyl; R 2 is C 3 -C 5 alkyl; R 3 is hydrogen, halo, trifluoromethyl, C 1 -C 4 alkyl, C 1 -C 4 alkoxy, phenoxy, cyano, nitro or C 2 -C 5 carboalkoxy; n is an integer from 1 to 5; -A-is - -(CH 2 ) m - R 4 is hydrogen, C,-C 4 alkyl, or -CH 2 Y; m is 0 or 1; and Y is halo, are insecticides.
Abstract:
Compounds having the formula in which R is methyl or ethyl, Y is sulfur or oxygen, and R₁ and R₂ are the same or different tertiary alkyl groups each having form 4 to 6 carbon atoms, are insecticides and nematicides, especially for control of soil insects and nematodes. Symmetrical compounds (R₁ = R₂) may be prepared by reaction of an alkali metal mercaptide with an alkyl (thio) phosphonic dihalide. The alkali metal mercaptide may be prepared by reaction of a tertiary alkyl mercaptan with an alkali metal or alkali metal hydride.
Abstract:
Compounds and compositions containing them, for insecticidal control having the formula in which R, is an alkyl group having from 1 to 3 carbon atoms, R 2 is an alkyl group having from 1 to 6 carbon atoms, and R 3 and R 4 are independently alkyl groups having from 1 to 6 carbon atoms, or R 3 and R 4 taken together form a ring having the formula in which m and n are each integers from 1 to 3 and X is oxygen or -CH 2 -, together with insecticidal compositions containing such compounds, and methods for controlling insects.
