Abstract
An electrochemical sulfonylation reaction of styrenes was developed in which sodium arylsulfinates were used as sulfonylating reagents, a catalytic amount of KI was used as a redox mediator, and Bu4NBF4 was used as the electrolyte. In addition to various styrenes, sodium arylsulfinates with either electron-donating or electron-withdrawing groups were tolerated.
