A copper-catalyzedcross-dehydrogenativeC–H/N–H coupling has been devised to access a series of N-arylated sulfoximines in high yield from 8-aminoquinoline-derived benzamides and sulfoximines. The reaction is scalable, and mechanistic studies favor the involvement of an organometallic pathway, where C–H bond cleavage is presumed to be the kinetically relevant step. The utility of sulfoximine-coupled

A photochemicalapproach for the preparation of α-keto-N-acyl sulfoximines from NH sulfoximines and gem-difluoroalkenes has been developed. In the presence of NBS, the reactions proceed in air without the need of a photocatalyst or additional oxidant. Results of mechanistic studies suggest that the two oxygens in the products stem from water and dioxygen.

Herein, we report an efficient electrochemical method for the synthesis of N-alkylated sulfoximines by electrochemical oxidative C(sp3)–H/N–Hcoupling of sulfoximines and diarylmethanes. In addition, we used the same conditions for electrochemicaldehydrogenativeamination of diarylmethanes with benzophenone imine as an aminating agent. The reactions showed good functional group tolerance and afforded

[Bis(difluoroacetoxy)iodo]benzene and NH-sulfoximines react to give new hypervalent iodine(III) reagents, which under photocatalysis transfer difluoroacetoxy and sulfoximidoyl groups to styrenes with high regioselectivity. The results of mechanistic investigations suggest the intermediacy of radicals and reveal the importance of the difluoroacetoxy group on the iodine reagent.
