PROCESSES OF HYDROGENATION OF UNSATURATED ORGANIC-COMPOUNDS IN THE PRESENCE OF NEW CATALYSTS BASED ON COMPLEXES OF PLATINUM-GROUP METALS WITH ALIPHATIC-AMINES

The main results of the synthesis and application of catalysts for the hydrogenation of unsaturated organic compounds based on complexes of platinum-group metals with aliphatic amines possessing fairly bulky alkyl groups (C-8 and above) are systematized. The common genesis of catalytically active systems with the participation of palladium, platinum, rhodium, and ruthenium is pointed out. This is manifested by the formation of hydride ligands on the metal on account of the hydrogen of the alkyl groups of the tertiary amine at the first stage of reaction of the initial platinum metal compound with the amine. The specific behaviour of catalysts for each of the metals is indicated. Examples are given of synergism in mixed systems including complexes of two metals.
