Hydrogenation of alkenes over nickel nanoparticles under atmospheric pressure of hydrogen was written by Mokhov, V. M.;Popov, Yu. V.;Nebykov, D. N.. And the article was included in Russian Journal of Organic Chemistry in 2016.Reference of 4435-14-7 This article mentions the following:
Nickel nanoparticles are an accessible catalyst which allows hydrogenation of unsaturated compounds to be accomplished under atm. pressure of hydrogen at relatively low temperatures Linear and cyclic alkenes, styrene and norbornene derivatives, as well as pinenes and camphene were smoothly hydrogenated under these conditions. In some cases, selective hydrogenation of unsaturated carbon-carbon bond is possible with the other functional group remaining intact. In the experiment, the researchers used many compounds, for example, 2-Cyclohexylacetonitrile (cas: 4435-14-7Reference of 4435-14-7).
2-Cyclohexylacetonitrile (cas: 4435-14-7) belongs to nitriles. Nitrile carbon shifts are in the range of 115–125 ppm whereas in isonitriles the shifts are around 155–165 ppm. Nitriles are susceptible to hydrogenation over diverse metal catalysts. The reaction can afford either the primary amine (RCH2NH2) or the tertiary amine ((RCH2)3N), depending on conditions.Reference of 4435-14-7
