An efficient one-pot approach for the synthesis of diaryl sulfoxides and diaryl sulfonesusing aryl thiols and aryl diazonium salts was developed. The use of a visible-light-driven silver catalysis and the subsequent singlet-oxygen-induced oxidation enabled selective synthesis of sulfoxides and sulfones in the absence of a photocatalyst. The reactions were carried out under mild reaction conditions;
An efficient cross-coupling of sodium or lithium sulfinates with aryl iodides, using a combination of nickel and photoredoxcatalysis, is described. The dual catalyst system enables a versatile synthesis of aryl sulfones at roomtemperature in good yields and displays a broad functional group compatibility. The potential utility of this method in the late-stage diversification of complex molecules
