Electrochemically Enable N -Sulfenylation/Phosphinylation of Sulfoximines via Oxidative Dehydrocoupling Reaction.

An electrochemical oxidative cross-coupling strategy for the synthesis of N -sulfenylsulfoximines from sulfoximines and thiols was accomplished, giving diverse N -sulfenylsulfoximines in moderate to good yields. Moreover, this strategy can be extended to construct the N-P bond of N -phosphinylated sulfoximines. With electrons as reagents, the oxidative dehydrogenation cross-coupling reaction proceeds smoothly in the absence of traditional redox reagents.
