Abstract

In this study, acetylation of anisole by acetic anhydride, catalyzed by bismuth triflate are described. The reaction was taken place under new generation monomode microwave irradiation (Discover oven), solvent-free condition. High yield was obtainted in short time. Good selectivities for the para- products were observed. Bismuth(III) triflate could be recycled and reused effectively.
