Abstract

The catalytic activity and reusability of the metallic Lewis acids, Cu(OTf)₂, Yb(OTf)₃, Sc(OTf)₃, In(OTf)₃, HfCl₄·(THF)₂ and InCl₃, for acetylation of alcohols with acetic anhydride and acetic acid has been examined in environmentally benign room temperature ionic liquids, [bmim][X] (bmim = 1-n-butyl-3-methylimidazolium, X = PF₆, BF₄, SbF₆). All of the catalysts effectively catalyzed the acetylation with acetic anhydride in an ionic liquid, [bmim][PF₆]. In direct acetylation with acetic acid, Yb(OTf)₃, Sc(OTf)₃ and InCl₃ showed excellent catalytic activity in the [bmim][PF₆] ionic liquid and were reasonably recycled.
