Rhodium-Catalyzed DirectorthoC–N Bond Formation of Aromatic Azo Compounds with Azides

Abstract

An efficient rhodium-catalyzed regioselective C-N bond formation of azo compounds in good to excellent yields through C-H bond functionalization using azides as the nitrogen source was developed. Alkyl, aryl, and sulfonyl azides could be efficiently assembled in this reaction with excellent functional group tolerance.
