Dry oxidation of benzoin under microwave irradiation

Abstract

Dry oxidation of benzoin with air under microwave irradiation gave benzil in excellent yield. Experimental results showed that both silica gel and acidic alumina were good supports and air was a good oxidant. Short reaction time (8～15min), excellent yield (92%～98%), inexpensive reagents and easy workup indicated the present procedure was efficient and convenient.

Key words: DRY METHOD, DIPHENYLDIKETONE, DIPHENYLHYDROXYETHANONE, AIR, OXIDATION REACTION, OXIDANT, MICROWAVE RADIATION, CARRIERS, SILICA GEL, ALUMINIUM OXIDE
