Transfer hydrogenation processes catalyzed by manganese organometallic complexes are comprehensively reviewed. The reaction scope includes the reduction of aldehydes, ketones, imines, polyaromatic nitrogen heterocycles, esters, nitriles, and semihydrogenation of internal alkynes. Special attention is devoted to ligand design for Mn-catalyzed asymmetric transfer hydrogenation of prochiral ketones leading to enantiomerically enriched alcohols.
