Electrogenerated Acid (EGA)-catalyzed Addition of Diaryl Disulfides to Carbon–Carbon Multiple Bonds

Abstract Addition of diaryl disulfides to carbon–carbon multiple bonds was achieved with a catalytic amount of an electrogenerated acid (EGA), which was produced by the electrolysis of Bu4N+B(C6F5)4−/CH2Cl2. The anti-addition products of two ArS groups across the carbon–carbon multiple bond were obtained in good yields.
