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.

An active nickel catalyst prepared in situ from a Ni(II) compound, phosphine ligand, and zinc powder was found to be an efficient catalyst system for the hydrocyanation of various alkenes using acetone cyanohydrin as a safer cyano source. The combination of NiCl2·6H2O and 1,3-bis(diphenylphosphino)propane was the most efficient catalyst precursor in DMF. Under the optimized conditions, various styrenes, heterocyclic alkenes, and aliphatic alkenes were converted to their corresponding nitriles in excellent yields.
