  • Polymer-bound cyclopentadiene metal carbonyl compounds and their ligand substitution derivatives
    Patent number: 4361497
    Abstract: Polymeric catalysts containing groups of the general formula: [--(C.sub.5 R.sub.4)Me(CO).sub.x L.sub.y ].sub.z, wherein (C.sub.5 R.sub.4) is a sustituted or unsubstituted cyclopentadiene group; Me is a transition metal; and L is alkyl or aryl phosphine, alkyl phosphite, nitrosyl, allyl, SnCl.sub.3, halogen or hydrogen. Such groups are bound to polymeric carriers such as polystyrene-based copolymers, silica gel or silicate glass. Processes for preparing such catalysts and methods for their use are also disclosed.
