    光驱动炔烃宝石加氢:Hoveyda–Grubbs 催化剂的分子内方法
    摘要:
    在 [(NHC)(η 6 -聚伞花烃)RuCl 2 ]存在下,内部炔烃的光驱动宝石氢化生成离散的钌卡宾络合物。当应用于适当设计的烯炔底物时,由此形成的反应性中间体将在复分解闭环中与束缚的烯烃结合,同时分裂出Hoveyda-Grubbs型络合物作为二级卡宾。这种用于烯烃复分解的经典催化剂的非常规方法可与现有方法相媲美,因为它安全、短、不含膦,并且使用现成的起始材料。

    摘要:
    [(NHC)(cymene)RuCl 2 ] (NHC=N-杂环卡宾)配合物引发内部炔烃的光驱动宝石-氢化,同时形成离散的 Grubbs 型钌卡宾物质。这种非正统的反应模式以“氢化复分解”反应的形式加以利用,该反应将烯炔底物转化为环状烯烃。在实际宝石氢化步骤中形成的钌卡宾的干预通过分离和结晶表征该系列的一个相当不寻常的代表在二取代的卡宾中心上带有不受限制的烷基而得到证明。

  • Light‐Driven <i>gem</i> Hydrogenation: An Orthogonal Entry into “Second‐Generation” Ruthenium Carbene Catalysts for Olefin Metathesis
    作者:Raphael J. Zachmann、Alois Fürstner
    DOI:10.1002/chem.202101176
    日期:2021.5.17
    The newly discovered light‐driven gem hydrogenation of alkynes opens an unconventional yet efficient entry into five‐coordinate Grubbs‐type ruthenium carbene complexes with cis‐disposed chloride ligands. Representatives of this class featuring a chelate substructure formed by an iodo‐substituted benzylidene unit react with (substituted) 2‐isopropoxystyrene to give prototypical “second‐generation” Grubbs‐Hoveyda
    新发现的炔烃的光驱动宝石氢化为非常规而高效地进入具有顺式配置的配体的五坐标Grubbs型卡宾配合物提供了条件。这类代表的特征是由取代的亚苄基单元形成的螯合物亚结构与(取代的)2-异丙氧基苯乙烯反应,生成原型的“第二代” Grubbs-Hoveyda络合物,用于烯烃复分解。这个古老的催化剂家族的新方法是安全和通用的,因为它使用三键而不是苯基重氮甲烷作为最终的卡宾源,并且不需要任何牺牲膦。

    A simple and efficient synthetic route to [RuCl2(NHC)(p-cymene)] and [Ru(CO3)(NHC)(p-cymene)] complexes making use of a weak base, under aerobic conditions, is reported. This method enables access to a series of NHC-ruthenium compounds with moderate to good yields under mild conditions. The Ru pre-catalysts were successfully used in olefin oxidation catalysis at low catalyst loading and reach complete

  • An Anionic Dinuclear Ruthenium Dihydrogen Complex of Relevance for Alkyne <i>gem</i> ‐Hydrogenation
    作者:Tobias Biberger、Nils Nöthling、Markus Leutzsch、Christopher P. Gordon、Christophe Copéret、Alois Fürstner

    日期:2022.6.13
    Cationic and neutral non-classical σ-H2 complexes are plentiful, but anionic ones remain exceedingly rare. It was during an investigation into the fate of a Ru-precatalyst in the light-driven alkyne gem-hydrogenation that such a species was encountered, which seems to be “first-in-class”: it lacks any substructures that counteract the negative charge and prevent oxidative insertion of the metal centers
    阳离子和中性非经典σ-H 2配合物非常丰富,但阴离子配合物仍然极其罕见。正是在对光驱动炔烃宝石氢化中预催化剂命运的调查中,遇到了这样一个物种,它似乎是“一流的”:它缺乏任何抵消负电荷的子结构并防止属中心氧化插入连接的 H−H 键中。
  • Synthesis and Catalytic Evaluation of Ruthenium−Arene Complexes Generated Using Imidazol(in)ium-2-carboxylates and Dithiocarboxylates
    作者:Lionel Delaude、Xavier Sauvage、Albert Demonceau、Johan Wouters
    DOI:10.1021/om9002363
    日期:2009.7.27
    The ability of five imidazol(in)ium-2-carboxylates and dithiocarboxylates bearing cyclohexyl, mesityl, or 2,6-diisopropylphenyl substituents on their nitrogen atoms to act as NHC precursors for in situ catalytic applications was probed in ruthenium-promoted ring-opening metathesis and atom transfer radical polymerizations. Results obtained with 1:2 mixtures of [RuCl2(p-cymene)](2) and NHC center dot CO2 adducts were in line with those reported previously starting from preformed [RuCl2-(p-cymene)(NHC)] complexes, whereas the NHC center dot CS2 zwitterions were almost completely inactive. To account for this dichotomy, the preparation of preformed ruthenium-arene complexes from [RuCk(p-cymene)](2) and NHC center dot CX2 inner salts was thoroughly investigated. As expected, imidazolium-2-carboxylates lost their CO2 moiety and afforded [RuCl2(p-cyrnene)(NHC)] complexes in high yields, whereas the NHC center dot CS, betaines retained their zwitterionic nature and led to cationic complexes of the [RuCl(p-cymene)(NHC center dot CS2)]PF6 type. These stable, 18-electron species are the first examples of well-defined transition-metal complexes bearing chelating NHC center dot CS2 ligands. They were characterized by various analytical techniques, and the molecular structure of [RuCl(p-cymene)([Mes center dot CS2)]PF6 was determined by X-ray diffraction analysis.
