Polymer-bound cyclopentadiene metal carbonyl compounds and their ligand substitution derivatives

摘要

Polymeric catalysts containing groups of the general formula: [-(C5R4)Me(CO)xLy]z, wherein (C5R4) is a sustituted or unsubstituted cyclopentadiene group; Me is a transition metal; and L is alkyl or aryl phosphine, alkyl phosphite, nitrosyl, allyl, SnCl3, 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.
