Asymmetric hydrogenation (AH) of double bonds has been one the most effective methods for preparation chiral molecules and synthesis important building blocks. In past 60 years, noble metals with bidentate ligands have shown marvelous reactivity enantioselectivity in asymmetric a series prochiral substrates. recent developing tridentate played an increasingly role AH. With modular frameworks variety functionalities on side arms, ligand complexes enable both reactivities stereoselectivities. Although great achievements made metal catalysts since 1990s, design earth abundant still high demand. This review summarizes development homogeneous hydrogenation.

Abstract Efficient hydrogen storage and release are essential for effective use of as an energy carrier. In principle, formic acid could be used a convenient medium via reversible CO 2 hydrogenation. However, noble metal-based catalysts currently needed to facilitate the (de)hydrogenation, produced during is generally released, resulting in undesirable emissions. Here we report α -amino acid-promoted system hydrogenation using Mn-pincer complex homogeneous catalyst. We observe good stability reusability catalyst lysine amino at high productivities (CO hydrogenation: total turnover number 2,000,000; dehydrogenation: 600,000). Employing potassium lysinate, achieve >80% H evolution efficiency >99.9% retention ten charge–discharge cycles, avoiding re-loading steps between each cycle. This process was scaled up by factor 18 without obvious drop productivity.
