Abstract

Abstract SO4 2−/SnO2 was employed for the acylation of a variety of alcohols, phenols, and amines under solvent??free conditions at room temperature. This method showed preferential selectivity for acetylation of the amino group in the presence of a hydroxyl group. The reported method is simple, mild, and environmentally viable, using several other acid anhydrides at room temperature.
