Electrochemical Catalysis of Coupling Reaction between Diselenide / Disulfide and Diazonium Salt

Abstract An electrochemically catalyzed coupling reaction of diselenides/disulfides with diazonium salts has been described. This method features short reaction time, mild conditions, low cost, high efficiency, and metal‐catalyst‐free operation, providing a novel route for synthesizing organoselenium compounds. Mechanistic studies such as cyclic voltammetry (CV), divided cell experiment, on–off electricity experiment, and radical trapping reactions support the electrochemical catalysis of the cross‐coupling process of diselenides with diazonium salts.
