Synthesis of Symmetrical Diaryl Sulfone by Homocoupling of Sodium Arylsulfinate

Abstract

An efficient practical homocoupling reaction of sodium arylsulfinate promoted by Cu(II) is reported whereby symmetrical diaryl sulfone derivatives are obtained with high selectivity and reactivity by intermolecular cross-coupling. This homocoupling reaction is tolerant to many functional groups and proceeds under mild conditions.
