    摘要: A process for the preparation of five-membered nitrogen-containing saturated heterocyclic compounds, such as pyrrolidone having high yield and selectivity results from carrying out a catalytic hydrogenation/amination of a five-membered heterocyclic anhydride or the corresponding acid in the presence of a complex catalyst containing ruthenium. Preferred catalysts have the formula:-

    In a representative embodiment maleic anhydride is converted to pyrrolidone by hydrogenation/amination in the presence of a ruthenium containing catalyst at a pressure of approximately 70 kg/cm 2 at a temperature of approximately 250°C.
