报道了在环境实验室条件下通过无金属(有机)分子间脱氢环化反应从未活化的芳烃和苯胺合成三环杂环咔唑的直接方法的发现。碘(III)用作唯一的试剂,从廉价的二乙酸苯基碘二乙酸酯化学计量或从PhI– m CPBA原位生成有机催化。在一个步骤中,两个串联的C–C和C–N键的形成反应就可以从两个不同的芳烃官能化三个C(sp 2)–H键和一个N(sp 3)–H键。
Reported herein is an environmentally benign electrochemical C−H bond dehydrogenative amination protocol for the construction of privileged carbazole moiety with broad generality. Preliminary mechanistic investigations implied a radical reaction pathway. Compared with traditional ionic routes, the scalable transition‐metal and exogenous‐oxidant free strategy highlighted the green and sustainable nature
