Diazenes are of particular importance in organic synthesis and routinely utilized as dyes, photoswitches, indicators, radical reaction initiators, food additives, and pharmaceuticals. In this work, a novel copper-catalyzed direct carbodiazenylation of cycloalkanes with aryldiazonium salts toward the synthesize of alkylarylazo compounds has been developed. The reaction can be carried out under redox
二氮烯在有机合成中特别重要,通常用作染料、光开关、指示剂、自由基反应引发剂、食品添加剂和药物。在这项工作中,开发了一种新型铜催化的环烷烃与芳基重氮盐的直接碳二烯基化反应,用于合成烷基芳基偶氮化合物。该反应可以在氧化还原中性条件下进行,该条件允许使用高度功能化的底物,并且可以以中等到良好的收率生产各种二氮烯。值得注意的是,该过程在温和条件下运行,然后可以直接制备吲哚。
