work capitalizes on the streamlined preparation of diverse N,N′-disubstituted sulfamides using Sulfur(VI) Fluoride Exchange (SuFEx) click chemistry that were subsequently subjected to electrochemical oxidation to afford the desired diazenes. The electrochemical nature of the reaction conditions obviated the need for chlorinating reagents, which considerably improved the sustainability of the overall
报道了通过工作台稳定的对称和不对称磺酰胺的阳极氧化电化学合成 1,2-二取代二氮烯。这项工作利用了使用硫 (VI) 氟化物交换 (SuFEx) 点击化学来简化制备各种N , N'-二取代磺酰胺,随后进行电化学氧化以获得所需的二氮烯。反应条件的电化学性质消除了对氯化试剂的需要,这大大提高了整个过程的可持续性。值得注意的是,除了烷基二氮烯的合成之外,这些较温和的条件也被证明能够形成偶氮苯,尽管产率较低。进行了机理实验来描绘反应途径并合理化N,N'-二芳基磺酰胺电氧化过程中观察到的副产物的形成。
