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.
