Electrochemical Oxidation Cross Dehydrogenative Coupling of Enamines and Thiophenols for the Synthesis of Vinyl Sulfides

Abstract A direct electrochemical oxidative cross dehydrogenative coupling reaction between enamines and thiophenols has been demonstrated. This strategy provides an effective, more economical, and environmentally friendly method to construct the C(sp 2 )‐S bond in the absence of chemical oxidants and transition metal catalysts. A variety of enamines and (hetero)aryl thiols are compatible with this transformation to afford the corresponding vinyl sulfides in moderate to excellent yields under undivided electrolytic cell conditions.
