Al(HSO4)3 Mediated for the Preparation of Primary Carbamates under Solvent-Free Conditions

Abstract

Al(HSO4)3 as an acidic salt, i.e. a mild, convenient and e cient reagent, was applied for the conversion of compounds containing a hydroxyl group to primary carbamates, at room temperature, with high yield and purity and without any epimerization, under solvent-free conditions.
