ABSTRACT OF THE DISCLOSURE: Cyclopentadienyl-metal-carbonyl compounds characterized in that they contain groups of the general formula: [-(c5R4)Me(co)xLy]Z wherein R is a hydrogen atom, a C1-4-alkyl group, a benzyl group, or a diphenylmethyl group; Me is a transition metal of the 6th, 7th or 8th subgroup of the Periodic System x is 1, 2 or 3, and in the case of compounds with metals of the 8th subgroup of the Periodic System, may also be equal to 0; L is a tri (alkyl-C1-3)-phosphine group, a triphenylphosphine group, a tri(alkyl-C1-3)-phosphite group, a nitrosyl group, allyl group, SnC13 group, a halogen atom or a hydrogen atom y is 0, 1 or 2; z is 1, 2, 3 or 4, which are covalently bound to a polymeric. support, either directly or through methylene, di(alkyl-C1-3)- methylene, (C1-3-alkyl)-phenyl-methylene, diphenylmethylene, C2-4-alkylene, di(C1-3-alkyl)-silylene, di(C1-3-alkoxy)- silylene, diphenyl-silylene, (alkyl-C1-3)-chloro-silylene, phenyl-chloro-silylene, dichloro-silylene groups or through analogous silylene groups substituted with two or three groups of the general formula -(C5R4)Me(CO)xLy in which R, Me, x, L and y have the aforesaid meanings. These compounds are particular- ly useful as catalysts in a variety of chemical reactions.
