Reduction of unsaturated adamantyl-containing nitriles with lithiumaluminumhydride in 2-methyltetrahydrofuran was examined. It was found that under the synthesis conditions a simultaneous reduction of the double bond and the nitrile group successfully occurred. The presence of bulky substituents in the α-position to the adamantyl moiety of nitriles led to a significant increase in the synthesis duration

Hydrogenation of carbonitriles catalyzed by nickel nanoparticles in isopropanol proceeds under atmospheric pressure of hydrogen within 6-15 h to yield mainly secondary amines. Hydrogenation of alpha-aminonitriles results in reductive decyanation. beta-Aminonitriles undergo hydrogenolysis at the nitrogen-carbon bond.

The regularities of reduction of adamantane-containing unsaturated nitriles with Raney nickel were studied. It was shown that in the reaction conditions simultaneous reduction of both the double bond and the nitrile group occurs. The reduction of 2-(5-hydroxyadamant-2-ylidene)alkyl nitriles requires a longer time.
