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.
