Acylation of Alcohols Using Acetic Acid and Oxidation of Alcohols Using Hydrogen Peroxide in the Presence of Benzyl Triphenylphosphonium Tribromide

Abstract

In this study benzyl triphenylphosphonium tribromide was prepared by oxidation of bromide ion with HNO₃ in the prescnce of benzyl triphenylphosphonium chloride in H₂O as solvent.

The application of BTPTB as catalyst for direct acetylation of alcohols with acetic acid was investigated. The acetylation reaction was performed at 70 ^oC in acetic acid. On the other hands, oxidation of benzylic alcohols was achived in high yield by BTPTB in the presence of hydrogen peroxide at 60 ^oC in CH₃CN as solvent.
