Abstract

PURPOSE: To obtain the titled compound useful as an insecticide and acaricide readily and in high purity, by depositing and removing cis- or trans- X from cis- or trans - cypermethrin respectively and selectively.
CONSTITUTION: A mixture consisting of an ester having the d-cis form on the acid side and the R- form on the alcohol side and an antipode thereof (cis X) or a mixture consisting of the d-trans form on the acid side and the R- form on the alcohol side and an antipode thereof ( trans X) is deposited from α-cyano-3-phenoxybenzyl ester of cis- or trans-2,2-dimethyl -3-(2,2-dichlorovinyl)cyclopropanecarboxylic acid ( cis- or trans-cypermethrin) respectively and removed by means of filtration or decantation to give cypermethrin rich in the cis Y form the mother liquor.
