Compounds of structure (a) are disclosed as effective insecticides, in which: A and B are independently lower alkyl; U is lower alkylidene, lower alkenylidene, or CH-Z, where Z is hydrogen, lower alkyl, lower cycloalkyl, or phenyl; R is phenyl or a dibenzocyclo(C5-8)alkyl, each optionally substituted, or (b), where R?3 and R4¿ are independently selected from phenyl, optionally substituted with halogen, lower alkyl, lower haloalkyl, lower alkoxy, lower haloalkoxy, lower alkenyl, or phenyl; R1 is selected from a variety of substituents, including 3-R2, where R2 is (c), where D, E and G are hydrogen, hydroxy, halogen, cyano, hydroxy, lower alkyl, lower haloalkyl, lower alkoxy, nitro, lower haloalkylsulfonyloxy, lower alkylcarboxylato, lower alkylcarbonylamino, lower alkylcarbonyl, lower alkoxycarbonyl, arylcarbonylamino; D and E taken together may form the group -O(CH¿2?)O-; J is hydrogen or lower alkyl; m is 2 or 3, n is 1, 2 or 3; and halogen is chlorine, bromine or fluorine. |
