    Abstract: A novel class of heterogeneous catalysts, containing Group VIII transition metals in combination with alkali organic compounds is prepared, such as potassium naphthalene on ruthenium on carbon. The catalysts are useful as heterogeneous catalysts in the hydrogenation of carboxylic acid esters. A process for producing the materials is described. The catalysts permit the process of the hydrogenation of carboxylic acid esters to primary alcohols to be conducted with the ester in the liquid phase at a temperature not exceeding about 150.degree. C. with high selectivity. Catalysts of Group VIII transition metals and alkali metal on carbon are also useful in such processes.

    Abstract: A novel process is described for the homogeneous hydrogenation of nitriles to primary amines utilizing anionic Group VIII metal hydride compositions as catalysts which contain phosphorus, arsenic or antimony organoligands. Use of these anionic catalysts allows the high yield hydrogenation of nitriles to primary amines to be conducted under mild conditions of temperature and pressure with high selectivity and eliminates the need for the presence of ammonia to suppress the formation of significant amounts of secondary and tertiary amines.

    Abstract: An improved process is described for the homogeneous hydrogenation of polycyclic aromatic hydrocarbons utilizing anionic Group VIII metal hydride compositions as catalysts which contain phosphorus, arsenic or antimony organoligands. Use of these anionic catalysts allows the process to be conducted under mild conditions of temperature and pressure with high selectivity for the production of partially hydrogenated derivatives of polycyclic aromatic hydrocarbons such as 1,2,3,4-tetrahydronaphthalene, and eliminates the need for the presence of base or carbon monoxide atmosphere in the process.
