摘要
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 beta-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.
