    摘要: A process for the preparation of novel aliphatic metal cluster compounds. The cluster compounds are prepared by reacting an alkyllithium such as n-butyllithium with a Group Ib metal halide or Group Ib metal halide complex such as gold chloride.triphenyl-phosphine. The resulting cluster compound is relatively stable.

    摘要: A process for the preparation of novel zero-valent mixed catalysts. The catalysts are prepared by the reaction of an organic metal cluster compound wherein one of the metals is lithium with a complex of a rhodium halide and an olefinic hydrocarbon ligand. The catalyst may, if desired, be deposited on a support such as alumina or silica. It is effective to catalyze the hydrogenation of organic compounds such as benzene, styrene and the like.

    摘要: A process for the hydrogenation of certain aromatic, olefinic and acetylenic compounds. The process is catalyzed by a zero-valent mixed metal catalyst which is in turn prepared by the reaction of an organic metal cluster compound wherein one of the metals is lithium with a complex of rhodium halide and an olefinic hydrocarbon ligand. The catalyst may, if desired, be deposited on a support such as alumina or silica. The hydrogenation process can, in many instances, be carried out under ordinary conditions, i.e., at room temperature and atmospheric pressure.
