interest in the realm of C-H functionalization because of the prevalence of nitrogen heterocycles and amines in pharmaceuticals and natural products. Reported here is a combined electrochemical/photochemical method for dehydrogenative C(sp3 )-H/N-H coupling that exhibits good reactivity with both sp2 and sp3 N-H bonds. The results show how use of iodide as an electrochemical mediator, in combination
C(sp3)-H键的直接胺化在CH功能化领域中引起广泛关注,因为在药品和天然产品中氮杂环和胺的普遍存在。此处报道的是用于脱氢C(sp3)-H / NH偶联的电化学/光化学组合方法,该方法与sp2和sp3 NH键均显示出良好的反应性。结果表明,使用碘化物作为电化学介体,结合光诱导的中间NI键的裂解,可以使电化学过程在低电极电位下进行。这种方法显着提高了电化学CH胺化的官能团相容性,例如,耐受在高电极电位下发生有害副反应的富电子芳族基团。
