Study on the Aromatic Transesterification Reaction Catalyzed by Phosphotungstic Acid

Hong‐Qiang He, Yu‐Wei Chang, Wei-Ming Xu

Abstract

A practical phosphotungstic acid-catalyzed aromatic transesterification reaction for the preparation of aryl benzoates has been developed. The transesterification method avoids the oxidation of the corresponding phenols to quinone compounds with easy operations, environmentally benign conditions and high yields of the products. It is noteworthy that in this process phosphotungstic acid can be reused and recycled. Keywords: Transesterification, phosphotungstic acid, aromatic esterification, aryl esters, conjugative effect.
