  摘要：

  对于稀溶液中的闭环复分解（RCM），已经进行了钌基复分解催化剂的周转数（TON）研究。出乎意料的结果表明，1种第一代复分解催化剂可以在比其第二代同行简单未取代的末端烯烃的RCM给予较高TON。特别地，1第一代格拉布催化剂表现出意想不到的高活性，特别是当相对于2种代催化剂。

  The syntheses and reactivity of seven different ruthenium-based metathesis catalysts are described. Ru(CF3COO)(2)(PCY3)(=CH-2-(2-PrO)C6H4) (1), Ru(CF3COO)(2)(1,3-dimesityldihydroimidazolin-2-ylidene)(=CH-2-(2-PrO)C6H4) (2), and Ru(CF3COO)2(PCY3)(1,3-dimesityldihydroimidazolin-2-ylidene)(=CH-C6H5) (3) were prepared via chlorine exchange by reacting RuCl2(PCy3)(2)(=CH-2-(2-PrO)C6H4), RuCl2(1,3-dimesityldihydroimidazolin-2-ylidene)(=CH-2-(2-PrO)C6H4), and RuCl2(PCy3)(1,3-dimesityldihydroimidazolin-2-ylidene)(=CHC6H5), respectively, with silver trifluoroacetate (Cy = cyclohexyl). In analogy, Ru(CF3CF2COO)(2)(1,3-dimesityldihydroimidazolin-2-ylidene)(=CH-2-(2-PrO)C6H4) (4) and Ru(CF3CF2CF2COO)1(1,3-dimesityldihydroimidazolin-2-ylidene)(=CH-2-(2-PrO)C6H4) (5) were prepared from RuCl2(1,3-dimesityldihydroimidazolin-2-ylidene)(=CH-2-(2-PrO)C6H4) via reaction with CF3CF2COOAg and CF3CF2CF2COOAg, respectively. Ru(C6F5COO)2(1,3-dimesityldihydroimidazolin-2-ylidene)(=CH-2-(2-PrO)C6H4) (6) and Ru(C6H4)2(1,3-dimesityldihydroimidazolin-2-ylidene)(=CH-2-(2-PrO)C6H4) (7) were prepared from RuCl2(1,3-dimesityldihydroimidazolin-2-ylidene)(=CH-2-(2-PrO)C6H4) via reaction with C6F5COOTI and C6F5OTI, respectively. Supported catalysts Ru(PS-DVB-CH(2)OOCCF(2)CF(2)CF2COO)(CF2COO)(PCy3)(1,3-dimesityldihydroimidazolin-2-ylidene)(=CHC6H5) (8), Ru(PS-DVBCH2OOCCF2CF2CF2COO)(CF3COO)(PCY3)(=CH-2-(2-PrO)C6H4) (9), and Ru(PS-DVB-CH2OOCCF2CF2CF2COO)(CF3COO)(1,3-dimesityldihydroimidazolin-2-ylidene)(=CH-2-(2-PrO)C6H4) (10) were synthesized by reaction of RuCl2(PCY3)(1,3-dimesityldihydroimidazolin-2-ylidene)( CHC6H5), RuCl(2)WYA CH-2-(2-PrO)C6H4), and RuCl2(1,3-dimesityldihydroimidazolin-2-ylidene)(=CH-2-(2-PrO)C6H4), respectively, with a perfluoroglutaric acid-derivatized poly(styrene-co-divinylbenzene) (PS-DVB) support (silver form). Halogen exchange in PCy3-containing systems had to be carried out in dichloromethane in order to suppress precipitation of AgCl center dot PCy3. The reactivity of all new catalysts in ring-closing metathesis (RCM) of hindered electron-rich and -poor substrates, respectively, at elevated temperature (45 degrees C) was compared with that of existing systems. Diethyl diallylinalonate (DEDAM, 11), diethyl allyl(2-methylallyl)malonate (12), NN-diallyl-p-toluenesulfonamide (13), N-benzyl-N-but-l-en-4-ylbut2-enecarboxylic amide (14), and N-allyl-N-(l-carboxymethyl)but-3-en-1-yl-p-toluenesulfonamide (15) were used as educts. Supported catalysts were prepared with high loadings (2.4, 22.1, and 160 mg of catalyst/g PS-DVB for 8, 9, and 10, respectively). Catalyst 8 showed higher and catalysts 9 and 10 sowed significantly reduced activities in RCM compared to their homogeneous analogues. Thus, with 8, turnover numbers (TONs) up to 4200 were realized in stirred-batch (carousel) RCM experiments.To eucidate the nature of the bound species, catalysts 8-10 were subjected to C-13- and P-31-MAS NMR spectroscopy. These investigations provided evidence for the proposed structures. Leaching of ruthenium into the reaction mixture was low, resulting in ruthenium contents < 85 ppb (ng/g) in the final RCM-derived products.
