Abstract
NEW MATERIAL:A substituted benzyl ester of formulaI[R1 is halogen; R2 is a group of formula II (R3 is H or methyl; R4 is cyclopentylidenemethyl, etc. when R3 is H, and methyl when R3 is methyl)].
USE: An insecticide, having much greater insecticidal action and rapid action than the conventional chrysanthemic esters, capable of exhibiting remarkable effects on injurious insects resistant to organophosphorus insecticides and/or carbamate insecticides, and rich in residual effects without remaining in the environment and low toxicity as opposed to organic chlorine insecticides.
PROCESS: A substituted benzyl alcohol of formula III or a reactive derivative thereof is reacted with a carboxylic acid of the formula R2COOH or a reactive derivative thereof to give the compound of formulaI.
