The electrochemical in-situ oxidative sulfonylation of phenols with sulfinic acids access to sulfonylated hydroquinones has been developed. A series of sulfonylated hydroquinones were prepared under mild mediator-, catalyst- and exogenous-oxidant-free conditions. Notably, such an electrochemical in-situ-oxidative synthetic strategy presented wide functional group tolerance and amenability to gram-scale
已经开发了苯酚与亚磺酸的电化学原位氧化磺酰化获得磺酰化氢醌。在温和的无介质、无催化剂和无外源氧化剂的条件下制备了一系列磺酰化氢醌。值得注意的是,这种电化学原位氧化合成策略表现出广泛的官能团耐受性和克级合成的适应性,产率为 62-80%。
