Polyvinylpolypyrrolidoniume Tribromide as an Efficient Catalyst for the Acetylation of Alcohols and Phenols

An efficient and versatile procedure for the acetylation of alcohols and phenols using acetic anhydride in the presence of a catalytic amount of polyvinylpolypyrrolidoniume tribromide has been successfully developed. Primary, secondary, and tertiary alcohols, as well as a selection of the phenolic compounds, have been successfully acetylated according to this procedure, with good to high yields being achieved over short reaction times.
