Abstract
Abstract We report the first example of homogeneously catalyzed hydrogenation of the N=N bond of azo compounds using a complex of an earth‐abundant‐metal. The hydrogenation reaction is catalyzed by a manganese pincer complex, proceeds under mild conditions, and yields amines, which makes this methodology a sustainable alternative route for the conversion of azo compounds. A plausible mechanism involving metal‐ligand cooperation and hydrazine intermediacy is proposed based on mechanistic studies. magnified image
