    名称:
    Coupling of terminal alkynes by RuHXL2 (X=Cl or N(SiMe3)2, L=PiPr3)
    摘要:
    The compounds RuL(2)HX, where L = P(i)Pr(3) and X = Cl or N(SiMe(3))(2), are catalyst precursors for dimerization of terminal alkynes to enynes and also to cumulenes at 23 degrees C; selectivity among these products is X-dependent, but not high. Conversion of Ru species onto the catalytic cycle was undetectably small, so alternative approaches to understanding the catalytic mechanism were employed: stoichiometric reactions, independent synthesis of candidate intermediates, and trapping with CO. These show the intermediacy of vinylidenes and vinyl compounds, and reveal conversion of cumulenes to the thermodynamically more stable enynes. (C) 2007 Elsevier B.V. All rights reserved.

  • Cross-metathesis reaction of functionalized and substituted olefins using group 8 transition metal carbene complexes as metathesis catalysts

    The invention pertains to the use of Group 8 transition metal carbene complexes as catalysts for olefin cross-metathesis reactions. In particular, ruthenium and osmium alkylidene complexes substituted with an N-heterocyclic carbene ligand are used to catalyze cross-metathesis reactions to provide a variety of substituted and functionalized olefins, including phosphonate-substituted olefins, directly halogenated olefins, 1,1,2-trisubstituted olefins, and quaternary allylic olefins. The invention further provides a method for creating functional diversity using the aforementioned complexes to catalyze cross-metathesis reactions of a first olefinic reactant, which may or may not be substituted with a functional group, with each of a plurality of different olefinic reactants, which may or may not be substituted with functional groups, to give a plurality of structurally distinct olefinic products. The methodology of the invention is also useful in facilitating the stereoselective synthesis of 1,2-disubstituted olefins in the cis configuration.
    该发明涉及将8族过渡金属卡宾配合物用作烯烃交叉⽐特⽅反应的催化剂。具体地,使用取代有N-杂环卡宾配体的钌和锇烷基亚烯配合物来催化交叉⽐特⽅反应,从而提供各种取代和官能化的烯烃,包括磷酸酯取代的烯烃,直接卤代的烯烃,1,1,2-三取代的烯烃和季铵烯烃。该发明还提供了一种利用上述配合物催化第一烯烃反应物(可能带有或不带有官能团)与多种不同烯烃反应物(可能带有或不带有官能团)进行交叉⽐特⽅反应,从而得到多种结构不同的烯烃产物的方法。该发明的方法还有助于促进顺式构型的1,2-二取代烯烃的立体选择性合成。

    The “Y” donor group (Y = −OMe, −SEt, −PPh2, −NH2, −NMe2, −Py, pyrrolidinyl, quinolyl) of the pincer-type ruthenium complexes RuHCl(CO)[κ3-YNP] has a dramatic influence on the catalytic activity in the dehydrogenative homocoupling and cross-coupling of ethanol and ester hydrogenation reactions. The observations are connected with the mechanisms of the catalytic reactions, and this paper provides evidence

Photophysical properties of Re−Ru−Re and the individual components with different or no covalent linkages are thoroughly investigated and compared. To elucidate the role of the single
