This work presents the results of a study of the catalytic activity and selectivity of multicomponent Raney nickel in the hydrogenation of phenylacetylene and hexine2.Hexin-2 is hydrogenated on Raney nickel selectively and stereospecifically, with the formation of mainly cis-hexene-2. The activity, selectivity and isomerizing ability of modified Raney nickel obtained from Ni-Al-Me and Ni-Al-Me1 -Me2 alloys (where Me-Cu, Ag, Zn, Ti, Zr, Sn, Pb, Ta, Bi, Cr, Mo, Mn, Fe, and Pd) in the reactions of hydrogenation of phenylacetylene, hexin-2 substantially depend on the nature of the additives introduced into the Ni-Al alloy.In hexin-2 hydrogenation reactions, multicomponent Raney nickel exhibit high stereociphicity. The yield ratio of cis-hexene-2 / trans-hexene-2 is 16-25, depending on the nature of the modifying additive.
