Abstract
NEW MATERIAL:The substituted benzyl ester of formulaI{R is group of formula II (R1 is H or methyl; R2 is cyclopentylidenemethyl, phenylthiovinyl, etc. when R1 is H, or R2 is methyl when R1 is methyl), group of formula III[R3 is H or group of formula IV (X is halogen); R4 is group of formula V, etc. when R3 is H, or R4 is H when R3 is group of formula IV]}.
EXAMPLE: α-Ethynyl-3-nitrobenzyl cis-2, 2-dimethyl-3-( 2, 2-dichlorovinyl )cyclopropanecarboxylate.
USE: Insecticide. It is a rapid-acting pyrethroidal compound having higher activity than conventional chrysanthemumic acid esters. It is remarkably effective even to insects resistant to organophosphorus insecticides, etc. It does not remain in the environment and has extremely low toxicity to man and animals.
PROCESS: The compound of formulaIis prepared by reacting e.g. the substituted benzyl alcohol or formula VI with the carboxylic acid halide of formula RCOX" (X" is halogen) in an inert solvent in the presence of a tert-amine.
