ABSTRACT:
A process for the preparation of novel zero-valent rhodium catalysts. The catalysts are prepared by the reaction of a hydrocarbyl-lithium compound with a hydrocarbon-soluble complex of a rhodium halide and a 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.
