Electrochemical oxidative dehydrogenative coupling of sulfoximines to construct N‐sulfenyl and N‐phosphinyl sulfoximines

Abstract Herein, an electrochemical oxidative approach for the synthesis of N‐sulfenyl and N‐phosphinyl sulfoximines has been established from readily available NH‐sulfoximines with thiophenols and diarylphosphine oxides. Utilizing the synergistic effect of halide salt and electrochemical oxidation, the desired products are obtained at room temperature in the absence of any acidic/basic/metallic additives.
