Abstract
Comprehensive Summary The selective oxidative sulfonylation of alkenes with selenium sulfonate depended on the reaction conditions. The electrochemical C—H sulfonylation proceeded smoothly to afford ( E )‐vinyl sulfones with good selectivity in an undivided cell without external oxidant. While aerobic trifunctionalization of alkenes occurred in the presence of KI in the air, which provides β ‐keto selenosulfones via the formation of C—O, C—S, and C—Se bonds in one‐pot. Following control experiments, a plausible mechanism is proposed to rationalize the experimental results.
