Catalysts having an unusual degree of selectivity for hydrogenation and other reactions are prepared by reacting an ion-exchange resin in particulate form with a solution of a metal compound to form a resin-metal complex in which the metal moiety is chemically bonded to the resin, e.g. by ionic or coordinate bonds, and reacting the complex with a reducing agent to reduce the metal to a state of lower valency. The metal may be Cu, Ag, Au, Zn, Cd, Hg, Sc, Y, La, Ac, Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W, Mn, Re, Fe, Co, Ni, Ru, Rh, Pd, Pt, Os and Ir and is preferably reduced to zero-valent state. After the reduction of the metal the catalyst may be treated with a regenerating agent to regenerate the functional groups of the catalyst. These catalyst can be used in reactions involving hydrogenation, carbonylation, or formylation of unsaturated compounds. |
