Abstract
Although extraordinary advances have been achieved by the transition-metal catalysis system, there is an urgent need to explore and develop alternative methodologies that are more environmentally friendly. Herein, we report an electrochemical chlorosulfonylation of alkenes using a wide range of sulfonyl chlorides with an inexpensive, degradable, and commercially available organoboron as a promoter. Furthermore, this protocol employs convergent paired electrolysis, reducing the need for sacrificial anodes and minimizing the extent of hydrogen evolution.
