Styrene as ligand and support : An excellent polymer‐supported ruthenium catalyst 1 has been developed in which the benzene rings of polystyrene are utilized as ligands to immobilize the ruthenium onto the polymer. In the presence of 1 , ring‐closing olefin metathesis proceeded smoothly to afford adducts in high yields. Furthermore, the catalyst was recovered quantitatively by filtration, and could be reused without loss of activity.
