  • Ruthenium Olefin Metathesis Catalysts with N-Heterocyclic Carbene Ligands Bearing <i>N</i>-Naphthyl Side Chains

    second-generation ruthenium-based olefin metathesis catalysts bearing N-naphthyl-substituted N-heterocyclic carbene (NHC) ligands have been prepared and fully characterized. By reaction with the appropriate NHC, these complexes are readily accessible in one synthesis step from the commercially available first-generation precursors [RuCl2(═CHPh)(PCy3)2] (Grubbs I, GI) or [RuCl2(═CH-o-iPrO-Ph)(PCy3)] (Hoveyda−Grubbs
    已经制备并充分表征了一系列带有N-萘基取代的N-杂环卡宾(NHC)配体的一系列第二代钌基烯烃复分解催化剂。通过与适当的NHC反应,可以在一个合成步骤中轻松地从市售的第一代前体[RuCl 2(═CHPh)(PCy 3)2 ](Grubbs I,GI)或[RuCl 2(═CH) - ø -我PRO-PH)(PCY 3)](格拉布I,HGI)通过简单地将一种膦配体与游离的NHC交换。对于这些催化剂,已经测量了标准底物在闭环复分解(RCM)中导致二取代以及三取代的烯烃随时间变化的转化率。当以含SIMb的母体SIMes为基准进行测试时(GII),大多数这些新的NHC结构在RCM中显示出增强的反应性。从这些比较研究中,收集到有价值的信息,这些信息表明,在萘基侧链上的烷基取代可以增强或降低催化性能,具体取决于这些烷基的体积和位置。已经在一系列代表性底物的RCM中,烯炔复分解反应以及交叉复分解(CM)中研究了性能最佳的预催化剂的行为。

  • Identification and Characterization of a New Family of Catalytically Highly Active Imidazolin-2-ylidenes
    作者:Xinjun Luan、Ronaldo Mariz、Michele Gatti、Chiara Costabile、Albert Poater、Luigi Cavallo、Anthony Linden、Reto Dorta

    日期:2008.5.1
    A new class of easily accessible and stable imidazolin-2-ylidenes has been synthesized where the side chains are comprised of substituted naphthyl units. Introduction of the naphthyl groups generates C-2-symmetric (rac) and C-s-symmetric (meso) atropisomers, and interconversion between the isomers is studied in detail both experimentally and computationally. Complete characterization of the carbenes includes rare examples of crystallographically characterized saturated NHC structures. Steric properties of the ligands and an investigation of their stability are also presented. In catalysis, the new ligands show versatility comparable to the most widely used NHCs IMes/SIMes or IPr/SIPr. Excellent catalytic results are obtained when either the NHC salts (ring-opening alkylation of epoxides), NHC-modified palladium compounds (C-C and C-N cross-couplings), or NHC-ruthenium complexes (ring-closing metathesis, RCM) are employed. In several cases, this new ligand family provides catalytic systems of higher reactivity than that observed with previously reported NHC compounds.

    comprised of substituted naphthyl units. This generates C2-symmetric (anti) and Cs-symmetric (syn) atropisomers. The interconversion between the isomers is studied in detail both for the N-heterocyclic carbene salts and the free carbenes through variable-temperature 1H NMR spectroscopic studies; activation free energies are calculated and can be linked to the substitution pattern of the naphthyl moieties
