A method is disclosed for preparing complexes of metals of the VIII Group of the Periodic Table, useful as hydrogenation catalysts. The method, as a single-step process, comprises reacting a polymeric complex containing V Group elements and VIII Group metal compounds directly with a metal atom which is directly bound to the V group element in the presence of a reducing substance. The reducing substance is selected among alkali metal and alkaline earth metal hydrides, mixed alkaline-III group element hydrides, organic metallic compounds of III Group metals, alkali metal and alkaline earth metal alkyls, Grignard compounds. |
