ACTION OF HETEROPOLY ACID AND RELATED OXIDES IN ACYLATION OF CHLOROBENZENE WITHO-CHLOROBENZOYL CHLORIDE

Abstract Heteropoly acids, MoO3, and calcined FeSO4 have been found to catalyze the acylation of chlorobenzene with O-chlorobenzoyl chloride. A kinetic study revealed that those catalysts are not active in their original forms, but the metal chlorides or metal complexes formed by reacting with chlorine are active for the acylation reaction.
