  • Patent number: 10550139
    Abstract: Embodiments of the present disclosure relate generally to novel achiral and chiral sulfur-, nitrogen- and phosphorus-containing ligands, designated as NNS-type, P(O)NS-type, PNS-type, SNNS-type, SNNP(O)-type, or SNNP-type polydentate ligands and transition metal complexes of these ligands, including iridium complexes having PNS-type and NNS-type ligands. The catalysts derived from these ligands and transition metal complexes may be used in a wide range of catalytic reactions, including hydrogenation and transfer hydrogenation of unsaturated organic compounds, dehydrogenation of alcohols and boranes, various dehydrogenative couplings, chemoselective hydrogenation of ?,?-unsaturated alcohols, and other catalytic transformations.

  • Patent number: 10487100
    Abstract: Disclosed herein are embodiments of chiral and achiral macrocyclic polydentate ligands and methods of preparing the same. Disclosed herein are also embodiments of metal coordination complexes derived from these macrocyclic polydentate ligands and methods of preparing the same. The metal coordination complexes described herein, can be used for a variety of catalytic reactions, including hydrogenation and transfer hydrogenation of unsaturated organic compounds, dehydrogenation of alcohols and boranes, an asymmetric Michael-type addition reaction, or an aerobic oxidative kinetic resolution of an organic compound, dehydrogenative couplings and other catalytic transformations.
