Synthesis of benzophenones using silica-gel supported Lewis acid catalyst

Article abstract of DOI:10.1016/S0040-4039(97)00109-3

Liquid phase benzoylation of activated as well as deactivated aromatics was carried out using silica gel supported FeCl₃ and benzotrichloride as a benzoylating agent. The catalyst was prepared by co-grinding FeCl₃ with silica gel in an agate mortar. The catalyst has a good shelf life of at least two months.
