Abstract
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.
Claims6
A process for the hydrogenation of aromatic, olefinic and acetylenic compounds comprising treating such compounds, which contain no nitrogen, phosphorous, tin or halogen, with hydrogen in the presence of a zero-valent mixed metal catalyst prepared by reacting an aliphatic metal cluster compound of the formula R.sub.x+y M.sub.x Li.sub.y where R is alkyl of 1-12 carbon atoms, M is a Group IB metal, x and y are each 1-4, and x+y is 2-8, with a metal halide complex of the formula RhX.sub.a L.sub.b wherein X is chlorine or bromine, L is an olefinic hydrocarbon ligand, a is 1-3 and b is 1-4, in a hydrocarbon solvent.
