Cover Feature: Monohydride‐Dichloro Rhodium(III) Complexes with Chiral Diphosphine Ligands as Catalysts for Asymmetric Hydrogenation of Olefinic Substrates (Chem. Eur. J. 40/2020)

Monohydride-dichloro rhodium(III) complexes bearing chiral diphosphine ligands stand as novel candidates for asymmetric hydrogenation of non-functionalized olefins. The sterically hindered chiral diphosphine ligand, (S)-DTBM-SEGPHOS, made it possible to isolate the rhodium(III) complex as a mononuclear complex which was confirmed by XRD analysis and DOSY NMR analysis. The novel monohydride rhodium(III) complex showed much higher enantioselectivity than classical dihydride rhodium systems on asymmetric hydrogenation of non-functionalized olefins.
