Abstract

A process for the preparation of α, 3-dichloro-4-cyclohexylphenylacetic acid which consists in reacting 4-cyclohexyl- α, α, 3-trichlorostyrene oxide with anhydrous hydrogen chloride, or with a concentrated aqueous solution of hydrogen chloride or with a strong alkaline solution of a metal hydroxide, followed by treatment with a halide of a group iib or iiia metal to form the desired product.
