Electrochemical dehydrogenative C–O bond formation for the synthesis of sultones was achieved. In the presence of K2CO3 and H2O, constant current electrolysis of [1,1′-biphenyl]-2-sulfonyl chloride afforded an aryl-fused sultone quantitatively. Under the optimized conditions, a variety of sultone derivatives were obtained. Control experiments suggest that the electrochemical oxidation of the sulfonates
实现了用于合成磺内酯的电化学脱氢 C-O 键形成。在K 2 CO 3和H 2 O存在下,恒流电解[1,1'-联苯]-2-磺酰氯定量得到芳基稠合磺内酯。在优化条件下,得到了多种磺内酯衍生物。对照实验表明,原位产生的磺酸盐的电化学氧化会提供磺基中间体。
