Catalytic hydrogenation of olefins using noble metal catalysts or pyrophoric RANEY nickel is of high importance in the chemical industry. From the point of view of green and sustainable chemistry, design and development of Earth-abundant, less toxic, and more environmentally friendly catalysts are highly desirable. Herein, we report the convenient preparation of active cobalt catalysts and their application in hydrogenations of a wide range of terminal and internal carbon-carbon double bonds in water under mild conditions. Catalysts are prepared on multi-gram scale by pyrolysis of cobalt acetate and uracil, guanine, adenine or l-tryptophan. The most active material Co-Ura/C-600 showed good productivity in industrially relevant hydrogenation of diisobutene to isooctane and in natural oil hardening.

Paragraph 0027-0028; 0036, (2017/04/27)
PROBLEM TO BE SOLVED: To provide a method for manufacturing a nitryl compound at good efficiency and safety under a moderate reaction condition. SOLUTION: In a manufacturing method of a nitryl compound, an organic compound having a carbon-carbon unsaturated bond and acetone cyanhydrin are reacted in the presence of bivalent nickel compound, an organic phosphorus compound and a metal powder to add a nitryl group to one carbon constituting the carbon-carbon unsaturated bond. The metal powder is selected from zinc, magnesium, aluminum and manganese. The nickel compound is preferably halide salt of nickel, carboxylate of nickel and β-diketo compound salt of nickel. The organic phosphorus compound is preferably triphenylphosphine. The reaction between the organic compound and the acetone cyanhydrin can be conducted at a reaction temperature of 85°C to 90°C in a solvent of an alcohol compound.

A new transfer hydrofunctionalization strategy to turnover H-MII-X complexes has enabled both intra- and intermolecular Mizoroki–Heck (MH)-type reactions of aryl cyanides that are challenging to realize under traditional, basic conditions. Initially, a cascade carbonickelation/MH reaction of 2-cyanostyrenes was achieved using a key alkyne transfer hydrocyanation step. Mechanistic experiments supported the proposed catalytic cycle, including the turnover-enabling transfer hydrocyanation step. The reactivity was then extended to the intermolecular MH reaction of benzonitriles and styrenes.
