The oxidative coupling reaction between hydroquinone or catechols and various sodiumbenzenesulfinates was investigated using the laccase from Trametes versicolor, in the presence of O2 in a phosphate buffer solution at room temperature to afford sulfonyl benzenediols in 75–95% yield.

A simple and efficient method for the synthesis of diarylsulfones using the coupling reaction of in-situ generated o-benzoquinones, promoted by potassium ferricyanide, and arylsulfinic acids has been developed. High product yields, a short reaction time, and mild reaction conditions are important features of this method.
