RuCl2(PPh3)3 has been attached to a phosphinated polymer support (phosphinated polystyrene crosslinked with 2percent divinylbenzene) and the reagent converted to the polymer supported analogue of RuClH(PPh3)3 in the presence of base.The polymer supported catalyst efficiently hydrogenates terminal olefins under ambient conditions.Hydrogenation of 1-hexene has revealed that the reaction rate is proportional to ,

and /(1 + ).The polymer support environment allows for selectivity in olefin hydrogenation and under suitable reaction conditions short chain terminal olefins are hydrogenated more rapidly than long chain terminal olefins.The extent of metal loading on the polymer and the reaction solvent composition also influence the reaction selectivity and these effects are discussed.
