A mild and efficient synthesis of diaryl sulfones from arylboronic acids and arylsulfonyl hydrazides is described. Promoted by cupric acetate and in the absence of additional ligand and base, the cross-coupling reaction could afford a series of unsymmetrical diaryl sulfones in moderate to good yields at room temperature under neutral and ambient conditions.

A convenient and e?cient synthesis of sulfones from sulfinates and aryl halides was developed. The reaction occurred under UV irradiation without transition metal catalyst or photocatalyst. A radical pathway via single-electron transfer (SET) of electron donor-acceptor (EDA) complex was proposed based on UV-vis spectroscopy, radical inhibiting and trapping experiments. (Figure presented.).

An efficient photoredox/nickel catalyzed sulfonylation reaction of aryl, heteroaryl, and vinyl halides has been achieved for the first time. This newly developed sulfonylation protocol provides a versatile method for the synthesis of diverse aromatic sulfones at room temperature and shows excellent functional group tolerance. The electrophilic coupling partners are not limited to aryl, heteroaryl, and vinyl bromides and iodides, but also includes less reactive aryl chlorides as suitable substrates for this transformation.
