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

A catalyzed synthesis of diarylsulfones with arylboronic acids and catalyst-free synthesis of arylvinyl and alkylvinyl sulfonesfromvinyl bronic acids or halides is reported.
cross-coupling reactions of aryl iodides and arylsulfonylhydrazides under ligand-enabled, Au(I)/Au(III) redox catalysis. This strategy operates under mild reaction conditions, requires no prefunctionalized aryl coupling partner, and works across several aryl iodides. The utility of this protocol is highlighted through the synthesis of various medicinally relevant biaryl sulfones. The reaction mechanism is supported
