  • Enantiopure base-metal catalysts for asymmetric catalysis and bis(imino)pyridine iron alkyl complexes for catalysis
    Patent number: 9394325
    Abstract: A transition metal-containing compound having a tridentate chiral ligand bound to iron, cobalt, or nickel. The tridentate ligands are bound to the metal via nitrogen, phosphorus, and/or arsenic atoms. The tridentate ligand has a chiral group bound at least one of the nitrogen, phosphorus, and arsenic atoms, and a blocking group may be bound to another one of the nitrogen, phosphorus, and arsenic atoms. The transition metal-containing compound is useful for the catalyzing the asymmetric hydrogenation of olefins.
