In this study, a novel copper-catalyzed direct carbodiazenylation method was developed for the synthesis of alkylarylazo compounds. The reaction is carried out under redox neutral conditions, allowing the use of highly functionalized substrates and producing a wide range of diazenes in moderate to good yields. Importantly, this process enables the straightforward preparation of indoles under mild conditions.
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 coppercatalyzed direct carbodiazenylation of cycloalkanes with aryldiazonium salts toward the synthesize of alkylarylazo compounds has been developed. The reaction can be carried out under redox neutral conditions which allow the use of highly functionalized substrates and a wide range of diazenes were produced in moderate to good yields. Notably, this process operates under mild conditions and then enables the preparation of indoles straightforwardly.
