开发了一种高效、环保的电催化方法合成N-酰基/磺酰基取代的次磺酰胺类化合物. 在单室电解池中, 不同取代基取代的缺电子胺和芳基硫醇反应良好, 以36%~98%的收率得到N—S键偶联产物. 初步的机理研究表明, 该反应可能通过自由基过程进行.

关键词: 电合成, N—S键构建, 次磺酰胺, 交叉偶联放氢反应

An efficient and environmentally friendly electrocatalytic protocol has been developed for synthesizing N-acyl/ sulfonyl sulfenamides. In an undivided cell, various electron-deficient groups substituted amines and aryl thiols react smoothly to afford the N—S bond formation products in 36%~98% yields. Preliminary mechanistic studies indicate that the reaction may work through a free radical process.

Key words: electrosynthesis, N—S bond formation, sulfenamides, cross coupling hydrogen evolution reaction
