Abstract

Abstract ZSM-5 has been modified as supported sulfuric acid (ZSM-5-SO 3 H) and introduced for the first time as a mild, convenient, reusable, and heterogeneous catalyst. Various types of aldehydes were efficiently converted to their 1, 1-diacetates using a catalytic amount of ZSM-5-SO 3 H in excellent yields under solvent-free and heterogeneous conditions at room temperature. The deprotection of 1, 1-diacetates has also been ...
