Abstract
NEW MATERIAL:Derivatives of isovaleric acid ester of formula I (when A is S, R1 is cycloalkyl or haloalkenyl etc. and R2 is H, R1 is alkoxyalkylcarbonyl and R2 is cyano, or R1 is indanyl and R2 is ethynyl; when A is NH, R1 is cycloalkyl etc. and R2 is cyano, or R1 is indenyl etc. and R2 is ethynyl; when A is CH2, R1 is haloalkylcarbonyl and R2 is H, R1 is cyanoalkyl and R2 is cyano, or R1 is alkylcarbonyl and R2 is ethynyl) and their optical and geometrical isomers.
EXAMPLE: α'-Cyano-m'-phenoxybenzyl ester of α-cyclohexylamino-isovaleric acid.
USE: Insecticide effective to various sanitary vermins and agricultural and horticultural vermins, low toxic to warm-blooded animals, and stable to light.
PROCESS: A compound of formula I is obtained by the reaction of a carboxylic acid of formula II etc. and an alcohol of formula III etc.
