This work reports an efficient sulfonylation reaction enabled by a visible-light-induced radical coupling reaction between phenyl/heterocyclic diazonium salts and sulfinates. Mechanistic experiments disclosed the formation of a versatile electron donor-acceptor (EDA) complex. This transformation is characterized by an easy operational procedure under mild conditions which avoids transition metals, ligands, catalysts, and oxidants.

We disclose herein the first transition-metal-and external oxidant/reductant-free visible-light-mediated synthesis of (un)symmetrical diaryl/alkyl aryl sulfones from arenediazonium tetrafluoroborates and sodium sulfinates using eosin Y as an organic photoredox catalyst. The utilization of visible light as an inexpensive and ecosustainable energy source, operational simplicity, ambient temperature and clean reaction in aqueous acetonitrile are the salient features of the developed protocol. The desired sulfones were also synthesized via a one-pot, two-step process directly from anilines and sulfinate salts in good to excellent yields.
Copper-mediated sulfonylation of aryl iodides and bromides with arylsulfonyl hydrazides in PEG-400

Sulfonylation using stable and readily available arylsulfonyl hydrazides and aryl iodides or bromides mediated by cupric acetate has been achieved. Using polyethylene glycol (PEG-400) as an eco-friendly medium, the coupling reaction could afford a series of unsymmetrical diaryl sulfones in moderate to good yields without the presence of additional ligands and base.
