摘要

采用可见光诱导的单锅串联光解法，制备了咔唑和吲哚衍生物。在没有任何光催化剂的情况下，芳基叠氮化和分子内C - H胺化在可见光照射下顺利进行，证明了芳烃偶氮-2-（2-硝基）丙烷的合成通用性。在温和的可见光光解条件下原位生成芳基叠氮化物中间体，展示了重氮盐的安全替代品-芳氮偶氮-2-（2-硝基）丙烷的合成通用性。

Tandem Photocatalyst‐Free Visible Light Aryl Azidation‐Intramolecular C−H Amination: One‐Pot Access to Carbazoles and Indoles from Areneazo‐2‐(2‐nitro)propanes

The visible light‐induced one‐pot tandem photolysis of areneazo‐2‐(2‐nitro)propanes was achieved to give carbazole and indole derivatives. The aryl azidation followed by an intramolecular C−H amination smoothly proceeded under visible light irradiation without any photocatalyst, demonstrating the synthetic versatility of areneazo‐2‐(2‐nitro)propanes. The in situ generation of aryl azide intermediates was executed under mild visible light photolysis conditions, showcasing the synthetic versatility of areneazo‐2‐(2‐nitro)propanes, a safe alternative of diazonium salts.

期刊介绍： Advanced Synthesis & Catalysis (ASC) is the leading primary journal in organic, organometallic, and applied chemistry. The high impact of ASC can be attributed to the unique focus of the journal, which publishes exciting new results from academic and industrial labs on efficient, practical, and environmentally friendly organic synthesis. While homogeneous, heterogeneous, organic, and enzyme catalysis are key technologies to achieve green synthesis, significant contributions to the same goal by synthesis design, reaction techniques, flow chemistry, and continuous processing, multiphase catalysis, green solvents, catalyst immobilization, and recycling, separation science, and process development are also featured in ASC. The Aims and Scope can be found in the Notice to Authors or on the first page of the table of contents in every issue.
