Selective synthesis of primary amines from nitriles is challenging in synthetic chemistry owing to the possible en route formation various and imines. Herein, we report a well-defined phosphine-free Mn(II)-pincer complex-catalyzed transfer hydrogenation corresponding with relatively unexplored hydrogen source (dimethylamine borane). The protocol proceeds under mild conditions broad substrate scope involving metal–ligand cooperation. Various control studies have been performed understand mechanism present strategy. gas chromatography analysis reaction mixture revealed evolution H2 through dehydrogenation dimethylamine borane. Detailed computational calculations were undertaken shed light on intermediates transition states involved during protocol.
