Abstract
Abstract Compounds of the general formula I ##STR1## wherein R 1 is hydrogen or a methoxy, ethoxy, propoxy, butoxy, tetrafluoroethoxy, methylthio, ethylthio, propylthio, fluoro, chloro, bromo, methyl, ethyl, or nitro group, and R 2 is hydrogen or a methyl group, or R 1 and R 2 together form a methylenedioxy group; R 3 is hydrogen, or a lower alkyl group, or one of the following groups (a) to (f): (a) 3-phenoxybenzyl (b) 2-benzyl-4-furylmethyl (c) α-cyano-3-phenoxybenzyl (d) 3,4-methylenedioxybenzyl (e) α-ethynyl-3-phenoxybenzyl (f) α-cyano-3-(4'-chlorophenoxy)-benzyl and Y 1 , Y 2 , Y 3 , Y 4 , Y 5 and Y 6 are the same or different groups and each is hydrogen or a fluoro, bromo or chloro group, with the proviso that when R 1 is hydrogen, fluoro, chloro, bromo or methyl and R 2 is hydrogen, then one of Y 1 to Y 6 is other than hydrogen. The compounds in which R 3 is one of groups (a) to (f) are insecticides.
