  • Patent number: 10010880
    Abstract: A new class of ligands derived from benzo[h]quinoline are described and these ligands are used to prepare several novel transition metal complexes. The complexes are preferably of the group VIII transition metals iron, ruthenium or osmium, with the benzo[h]quinolone ligands acting as tridentate ligands. The complexes described are proved to be very active catalysts for the reduction of ketones and aldehydes to alcohols, via hydrogen transfer and hydrogenation reactions. These compounds hence can be usefully employed as catalysts in said reduction reactions.

  • Patent number: 9925528
    Abstract: The invention provides simple small molecule, non-heme iron catalyst systems with broad substrate scope that can predictably enhance or overturn a substrate's inherent reactivity preference for sp3-hybridized C—H bond oxidation. The invention also provides methods for selective aliphatic C—H bond oxidation. Furthermore, a structure-based catalyst reactivity model is disclosed that quantitatively correlates the innate physical properties of the substrate to the site-selectivities observed as a function of the catalyst. The catalyst systems can be used in combination with oxidants such as hydrogen peroxide to effect highly selective oxidations of unactivated sp3 C—H bonds over a broad range of substrates.
