An electrochemical sulfonylation reaction of styrenes with sodium arylsulfinates as sulfonylating reagents, a catalytic amount of KI as a redox mediator, and Bu4NBF4 as the electrolyte provides vinyl sulfones in good yields. Substrates bearing either electron-donating or electron-withdrawing groups are tolerated.
