Process for producing a 3-methyl-2-(4-halophenyl)butyronitrile

摘要

A process for producing 3-methyl-2-(4-halophenyl)butyronitrile, which is an important intermediate for the production of insecticides, in a high yield and a high purity even on a commercial scale comprising reacting a p-halophenylacetonitrile having a p-halobenzyl alcohol content of not more than 1.0 % by weight, with an isopropyl halide having an isopropyl alcohol content of not more than 1.0 % by weight.
