An efficient electrochemically oxidative α-C?H thiocyanation and sulfenylation of ketones has been developed in a simple undivided cell under constant current condition.?The electrochemistry performs using NaI as the redox catalyst and heterogeneous solid salt Amberlyst-15(H) (A-15(H)) as proton catalyst?without the addition of external conductive salts. The protocol proved to be practical since the solid salt could be reused in up to five consecutive gram-scale runs without significant decrease in efficiency. Control experiments and cyclic voltammetry analysis disclose that the reaction proceeds likely via a cascade α-halogenation and subsequent thiocyanation or sulfenylation. (Figure presented.).
