Sulfonylation using stable and readily available arylsulfonyl hydrazides and aryliodides or bromides mediated by cupric acetate has been achieved. Using polyethyleneglycol (PEG-400) as an eco-friendly medium, the couplingreaction could afford a series of unsymmetrical diaryl sulfones in moderate to good yields without the presence of additional ligands and base.
A new and efficient approach adopting copper-catalyzed cross-coupling of sulfonyl hydrazides with aryltriazenes has been developed to synthesize aryl sulfones using Brønsted acidic ionic liquid as promoter under ambient conditions. The process employs stable and easy to handle reacting partners, and is endowed with broad substrate scope.

[reaction: see text] A simple and efficient method for the synthesis of unsymmetrical diaryl sulfones using the palladium-catalyzedcoupling of aryl boronic acids and arylsulfonyl chlorides has been developed. High product yields, a short reaction time, and mild reaction conditions are important features of this method.
An efficient and general protocol for the synthesis of diarylsulfones via the metal-free coupling of readily available diaryliodonium salts and arenesulfinates in PEG-400 under microwave irradiation has been developed. Utilizing this metal-free and eco-friendly protocol, we have prepared various diarylsulfones in high yields and shorter reaction times under mild conditions. Furthermore, the coupling
