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.

A new procedure for the oxidation of sulfides to sulfones utilizing heterogeneous ruthenium reagent has been developed. A small amount of ruthenium trichloride (RuCl3) supported on alumina and excess sodium metaperiodate (NaIO4) was used to produce the ruthenium oxidizing catalyst in the reaction mixture. Sodium metaperiodate oxidized the pre-catalyst RuCl3 to RuO4 and also maintained a constant supply of RuO4 by oxidizing lower valent ruthenium ions during the course of the reaction. An environmentally friendly solvent mixture of dimethyl carbonate (DMC) and water was employed. A wide variety of aromatic sulfides were oxidized to sulfones in good to excellent yields by utilizing this procedure.

The oxidation of organo-sulfides to sulfones has been accomplished using an easily accessible bifunctional ionic liquid, [pmim]IO4 in the absence of any other oxidants, metal and organic solvent at ambient temperature. A variety of sulfides including dialkyl, aryl-alkyl, diaryl, and aryl-hetero aryl have been oxidized to the corresponding functionalized sulfones in high yields by this procedure.
