通过电化学氧化方法, 实现了酚与亚磺酸钠类化合物中等到高收率的磺酰化反应, 获得了具有良好官能团耐受性的芳基磺酰酯. 杀螨酯的合成和克级反应的实施, 验证了该绿色方案的实用性. 循环伏安实验表明, 标准条件下亚磺酸盐的氧化先于酚的氧化, 且该过程涉及自由基.

An electrochemical oxidative sulfonylation of phenols with sodium sulfinates has been established to produce arylsulfonyl esters with good functional group tolerance in moderate to high yields. The synthesis of chlorfenson and a gram-scale reaction have been performed to evaluate the practicality of this green protocol. Cyclic voltammetry experiments indicate that the oxidation of sulfinate occurs prior to that of phenol substrate under standard conditions, and free radical is involved in the process.

Key words: electrochemical synthesis, aryl sulfonates, metal-free conditions, green method
