A Ni0 σ-Borane Complex Bearing a Rigid Bidentate Borane/Phosphine Ligand: Boryl Complex Formation by Oxidative Dehydrochloroborylation and Catalytic Activity for Ethylene Polymerization

While of interest, synthetically feasible access to boryl ligands and complexes remains limited, meaning such complexes remain underexploited in catalysis. For bidentate boryl ligands, oxidative addition of boranes to low-valent IrI or Pt0 are the only examples yet reported. As part of our interest in developing improved group 10 ethylene polymerization catalysts, we present here an optimized synthesis of a novel, rigid borane/phosphine ligand and its Ni0 σ-borane complex. From the latter, an unprecedented oxidative dehydrochloroborylation, to give a NiII boryl complex, was achieved. Furthermore, this new B/P ligand allowed the nickel-catalyzed polymerization of ethylene, which suggests that Ni0 σ-hydroborane complexes act as masked NiII boryl hydride reagents.

Quinoline diamine-containing fourth subgroup metal complex and application thereof

The invention relates to the technical field of olefin polymerization catalysts, and particularly discloses a quinoline diamine-containing fourth subgroup metal complex and application thereof. The quinoline diamine-containing fourth subgroup metal complex has the following structure: the quinoline diamine-containing fourth subgroup metal complex provided by the invention can catalyze ethylene homopolymerisation with high activity to obtain polyethylene with high molecular weight, and catalyze ethylene and [alpha]-olefin with high activity to copolymerize to generate a copolymer with medium to high molecular weight and insertion amount; and therefore, the problem that an existing olefin polymerization catalyst cannot generate a high-molecular-weight polymer while improving the catalytic activity is solved, and the olefin polymerization catalyst has a wide application prospect.

Consecutive Intermolecular Reductive Amination/Asymmetric Hydrogenation: Facile Access to Sterically Tunable Chiral Vicinal Diamines and N-Heterocyclic Carbenes

A highly enantioselective iridium- or ruthenium-catalyzed intermolecular reductive amination/asymmetric hydrogenation relay with 2-quinoline aldehydes and aromatic amines has been developed. A broad range of sterically tunable chiral N,N′-diaryl vicinal diamines were obtained in high yields (up to 95 %) with excellent enantioselectivity (up to >99 % ee). The resulting chiral diamines could be readily transformed into sterically hindered chiral N-heterocyclic carbene (NHC) precursors, which are otherwise difficult to access. The usefulness of this synthetic approach was further demonstrated by the successful application of one of the chiral vicinal diamines and chiral NHC ligands in a transition-metal-catalyzed asymmetric Suzuki–Miyaura cross-coupling reaction and asymmetric ring-opening cross-metathesis, respectively.
