Abstract
Novel polymer supported catalysts are prepared by irradiation of low valent transition metal compounds such as iron carbonyl in the presence of solid polymers containing ligands such as phosphinated polystyrene. Hydrogenation of olefins at ambient conditions has been demonstrated.
Claims5
A method of preparing an olefin addition catalyst comprising the steps of:
- forming a solution of a low valent transition metal coordination compound in organic solvent;
- irradiating the solution with ultraviolet radiation to form photochemically generated transition metal species;
- combining an insoluble organic polymeric support having ligands for said metal with said species;
- and
- attaching said photochemically generated species to said ligands in an amount of at least 0.1% by weight of metal on said polymeric support.
