The catalytic (hydrogenation of propylene), asymmetric (enantioselective hydrogenation of ethyl acetoacetate), and magnetic properties of intermetallic compounds with the composition Ln(NiM)/sub 5/(IMC), where Ln = La, Sm, Gd; M = Ti, V, Cr, Mn, Cu, and of their hydrides have been studied. The data obtained indicate that the catalytic activity of the above compounds in both reactions is due to structural peculiarities of IMC and to the affinity of IMC to H/sub 2/. The observed changes in the total and the optical yield of the product of hydrogenation in the presence of IMC hydrides, modified with R,R-(+) tartaric acid, as functions of the nature of d-metals and their combinations, in the initial complex catalyst lead to the assumption that different metal tartrate complexes are formed on the hydride surface which act as centers of enantioselective hydrogenation.
