This invention relates to nickel catalysts with alkali ions for homopolymerization and copolymerization.

A solution consisting of: a poly(a-olefin) (PAO) selected from the group consisting of PAO.sub.283, PAO.sub.432, and PAO.sub.687; and a reactive organometallic reagent selected from the group consisting of n-butyllithium, sec-butyllithium, tert-butyllithium, n-butyllithium in hexane, sec-butyllithium in cyclohexane, and tert-butyllithium in pentane.

A nanofibrous catalyst for in the electrolyzer and methods of making the catalyst. The catalysts are composed of highly porous transition metal carbonitrides, metal oxides or perovskites derived from the metal-organic frameworks and integrated into a 3D porous nano-network electrode architecture. The catalysts are low-cost, highly active toward OER, with excellent conductivity yet resistant to the oxidation under high potential operable under both acidic and alkaline environments.

A chiral bimetallic cooperative catalysis system containing a chelating ligand and use thereof in asymmetric synthesis of bedaquiline are provided. Specifically, in the chiral bimetallic cooperative catalysis system, an equilibrium constant of a reaction is increased by the chelating ligand formed by an achiral secondary amine and chiral lithium aminoalcohol, thereby promoting an addition reaction between 6-bromo-3-benzyl-2-methoxyquinoline (I) and 3-dimethylamino-1-naphthyl-1-propanone (II) to move forward. By means of the bimetallic cooperative catalysis system, the yield of the target product (1R,2S)-bedaquiline is obviously increased.
