PROCESS FOR THE PREPARATION OF PHENYL ALKANSANIC M-PHENOXY BENZYL ESTERS

摘要

This invention provides a novel m- phenoxybenzyl ester derivative which is useful as an insecticidal and acaracidal agent. The novel compound is (+/-)- alpha -cyano-m-phenoxybenzyl (+)- alpha -isopropyl-4- difluoromethoxyphenylacetate which may be obtained by reaction of a (+)- alpha -isopropyl-4-difluoromethoxyacetyl halide with (+/-)- alpha -cyano-m- phenoxybenzyl alcohol. The structure of the novel compound is represented by the formula: IMAGE The novel compound exhibits outstanding activity as a contact and stomach poison for ixodide ticks and for a wide variety of insects.
