Herein, we report a C-N coupling reaction via antiaromatic endocyclic nitrenium ions. The nitrenium ion intermediate was generated by a combination of iodine(III) reagent PhI(OCOCF) and the N-H center of benzimidazole units at ambient laboratory conditions. Metal-free synthesis of benzimidazole-fused phenanthridine derivatives was achieved in good to excellent yields.
在此，我们报道了一种通过反芳香性内环氮鎓离子进行的C-N偶联反应。在实验室环境条件下，通过碘（III）试剂PhI（OCOCF）与苯并咪唑单元的N-H中心相结合生成氮鎓离子中间体。以良好至优异的产率实现了苯并咪唑稠合菲啶衍生物的无金属合成。
