SYNTHESIS OF BENZYL ESTERS OF 2,2-DIMETHYL-3-(4-DIFLUOROMETHOXYPHENYL)CYCLOPROPANE CARBOXYLIC ACID - CYCLIC ANALOGS OF PYRETHROID FLUOROCITRINATE

3-Phenoxybenzyl and α-cyano-3-phenoxybenzyl esters of 2,2-dimethyl-3-(4-difluoromethoxyphenyl)cyclopropane carboxylic acid have been synthesized.The latter compound, which is the cyclopropane analog of pyrethroid fluorocitrinate, has moderate insecticide activity toward the housefly.

Preparation of phenoxybenzyl esters

Phenoxybenzyl esters are prepared by neutralizing an aqueous solution of a carboxylic acid and contacting the neutralized solution with a solution of phenoxybenzyl halide in a water-immiscible base in the presence of a phase transfer catalyst.
