New compounds are described that fall within the general formula I
wherein R' is hydrogen or a methoxy, ethoxy, propoxy, butoxy, tetrafluoroethoxy, methylthio, ethylthio, propylthio, fluoro, chloro, bromo, methyl, ethyl, or nitro group, and R2 is hydrogen or a methyl group, or R' and R2 together form a methylenedioxy group; and R3 is hydrogen, or halogen or an esterifying group, as well as other derivatives of the acid. The I esterifying group may be a lower alkyl group, or one of the following groups (a) to (f):-
(a) 3-phenoxybenzyl
(b) 2-benzyl-4-furylmethyl
(c) a-cyano-3-phenoxybenzyl
(d) 3,4-methylenedioxybenzyl
(e) a-ethynyl-3-phenoxybenzyl
(f) α-cyano-3-(4'-chlorophenoxyl)-benzyl
and Y1, y2, Y3, Y4, Y5 and Y6 are the same or different groups and each is hydrogen or a fluoro, bromo or chloro group, with the proviso that when R' is fluoro, chloro, bromo or methyl and R2 is hydrogen, then one of Y' to Y6 is other than hydrogen. Processes of making the compounds are described. The compounds in which R3 is one of groups (a) to (f) are insecticides and insecticidal methods and compositions containing them are described.
