Abstract
Benzoic acid (4-(2-propoxy)-3-vinylphenyl) ester (1), the divinyl compounds terephthalic acid bis(4-(2-propoxy)-3-vinylphenyl) ester (2) and bis(4-(2-propoxy)-3-vinylphenoxy)diphenylsilane (3), and the trivinyl compound benzene-1,3,5-tricarboxylic acid tris(4-(2-propoxy)-3-vinylphenyl) ester (4) were used for the synthesis of a series of ruthenium-based mono-, bi-, and trinuclear metathesis catalysts, i.e., RuX2(IMesH2)(CH-2-(2-PrO)-C6H3-5-OOCC6H5) (X = Cl, I1a; X = OOCCF3, I1b), 1,4-[RuX2(IMesH2)(CH-2-(2-PrO)-C6H3-5-OOC)]2C6H4 (X = Cl, I2a; X = OOCCF3, I2b), [RuX2(IMesH2)(CH-2-(2-PrO)-C6H3-5-O)]2SiPh2 (X = Cl, I3a; X = OOCCF3, I3b), and 1,3,5-[RuX2(IMesH2)(CH-2-(2-PrO)-C6H3-5-OOC)]3C6H3 (X = Cl, I4a; X = OOCCF3, I4b) (IMesH2 = 1,3-dimesityl-4,5-dihydroimidazol-2-ylidene), where the corresponding trifluoroacetate-derived systems were prepared from the parent dichloro-substituted initiators via reaction with CF3COOAg. Initiators I1a−I4a and I1b−I4b were used for the cyclopolymerization of a series of 1,6-h...
