A stereoselective synthesis of (E)-vinyl sulfones has been developed via electrochemical oxidative N–S bond cleavage of aromatic sulfonylhydrazides, followed by cross-coupling reactions with cinnamic acids to form the C–S bond. The protocol proceeded smoothly to afford (E)-vinyl sulfones in good yields with wide substrate scope under metal-free and halogen-free conditions.

肉桂酸与芳香族磺酰肼的电化学脱羧磺酰化为乙烯基砜

通过芳族磺酰肼的电化学氧化N-S键裂解，然后与肉桂酸交叉偶联反应形成C-S键，已开发出立体选择性合成（E）-乙烯基砜的方法。该方案进展顺利，在无金属和无卤素条件下，以高收率得到了（E）-乙烯基砜，具有广泛的底物范围。
