✦ Synopsis

Liquid phase benzoylation of activated as well as deactivated aromatics was carried out using silica gel supported FeCI 3 and benzotrichloride as a benzoylating agent. The catalyst was prepared by co-grinding FeCI 3 with silica gel in an agate mortar. The catalyst has a good shelf life of at least two months.
