Aluminium triflate (0.01–0.1 mol %) was found to be an efficientcatalyst for the acylation of alcohols, phenols, thiols and sugars with acetic anhydride in high yields undersolvent-freeconditions in a short reaction time at room temperature. Racemization of optically active alcohols and epimerization of sugars were not observed. The acylation efficacy of various acyl donors was also investigated
