Microwave assisted synthesis of benzophenone and acetophenone ethylene ketals

Abstract

A simple and convenient synthesis of acetophenone and benzophenone ethylene ketals was elaborated by performing the reaction of ethylene glycol in toluene in the presence of PTSA, under microwave irradiation with simultaneous removal of the water so formed. Under these conditions 100 % conversion and high yields were obtained within short reaction times. ©ARKAT USA, Inc.
