摘要: The ruthenium catalysts (PCy3)2Ru(C(H)Ph)Cl2 (1), (PCy3)Ru(IMes)(C(H)Ph)Cl2 (2), (PCy3)Ru(SIMes)(C(H)Ph)Cl2 (3), (PCyp3)Ru(IMes)(CHCHC(CH3)2)Cl2 (4), and (PCy3)Ru(IPr)(3-phenylindenylid-1-ene)Cl2 (5), where IMes = 1,3-bis(2,4,6-trimethylphenyl)imidazol-2-ylidene, SIMes = 1,3-bis(2,4,6-trimethylphenyl)-4,5-dihydroimidazol-2-ylidene, IPr = 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene, Cy = cyclohexyl, and Cpy = cyclopentyl, have been grafted to polymer supports and found to be effective heterogeneous catalysts for ring-closing metathesis. In some cases, they are recyclable, show comparable reactivity to their homogeneous counterparts, tolerate functional groups, and perform very well with unsubstituted dienes.
