Visible light induces C-C-bond cleavage reactions of ketones, which can be utilized forN-acylations of sulfoximines. No (photo)catalyst is required, and the reactions occur at ambient temperature in air. The substrate scope is broad for both ketones and sulfoximines. For convertingNH-sulfoximines, the presence of NBS is essential.

A copper-catalyzed methodology for the preparations of N-aroylated sulfoximines from methylarenes was herein demonstrated. The transformation proceeded with the assistance of external oxidant tert-butyl hydroperoxide, requiring for no additional solvents or ligands. The good compatibility and high efficiency of the newly developed protocol were well described by 21 examples and up to 91% yields. Moreover, the protocol was proved by the control reactions to proceed through a radical pathway.

A copper-catalyzed oxidative decarboxylative coupling of α-keto acids with NH-sulfoximines has been developed. With CuBr as the catalyst and K2S2O8 as the oxidant, this reaction enables the formation of a C-N bond and gives N-aroylsulfoximine products in moderate to excellent yields. The reaction mechanism is likely to involve the generation of a reactive aroyl radical intermediate.
