  • Stable, Yet Highly Reactive Nonclassical Iron(II) Polyhydride Pincer Complexes: <i>Z</i>-Selective Dimerization and Hydroboration of Terminal Alkynes

    polyhydride complexes containing tridentate PNP pincer-type ligands is described. These compounds of the general formula [Fe(PNP)(H)2(η2-H2)] exhibit remarkable reactivity toward terminal alkynes. They efficiently promote the catalytic dimerization of aryl acetylenes giving the corresponding conjugated 1,3-enynes in excellent yields with low catalyst loadings. When the reaction is carried out in the presence

  • Cobalt Catalyzed <i>Z</i>-Selective Hydroboration of Terminal Alkynes and Elucidation of the Origin of Selectivity

    A bis(imino)pyridine cotalt-catalyzed hydroboration of terminal,,alkynes with HBPin (Pin = pinacolate) with high yield and (Z)selectivity for synthetically valuable vinylboronate esters is described. Deuterium labeling studies Stoichiometric experiments, and isolation of catalytically relevant intermediats support a mechanism involving;selective insertion of,an alkynyl-boronate ester into a Co-H bond, a pathway distinct from known precious metal catalysts, where metal Vinylidene intermediates have been proposed to account for the observed (Z) selectivity. The identity Of the imine substituents dictates the relative rates of activation of the cobalt precatalyst with HBPin or the terminal alkyne and, as a consequence, is responsible for the stereochemical outcome of the catalytic reaction.
  • Ruthenium Catalyzed Hydroboration of Terminal Alkynes to <i>Z</i>-Vinylboronates
    作者:Chidambaram Gunanathan、Markus Hölscher、Fangfang Pan、Walter Leitner

    日期:2012.9.5
    The nonclassical ruthenium hydride pincer complex [Ru(PNP)(H)(2)(H-2)] 1 (PNP = 1,3-bis(di-tert-butyl-phosphinomethyl)pyridine) catalyzes the anti-Markovnikov addition of pinacolborane to terminal alkynes yielding Z-vinylboronates at mild conditions. The complex [Ru(PNP)(H)(2)(HBpin)] 2 (HBpin = pinacolborane), which was identified at the end of the reaction and prepared independently, is proposed as the direct precursor to the catalytic cycle involving rearrangement of coordinated alkyne to Z-vinylidene as a key step for the apparent trans-hydroboration.

    terpyridine (tpy) ligands via 2′/6′-, 3′/5′-, or 4′-selective alkylation of the central pyridine ring. The reaction is mediated by the most abundant metal in the Earth’s crust, aluminum (Al), and depending on the conditions employed, exhibits ionic or radical character as suggested by experimental and computational analysis. In the latter case, intermediate formation of an AlIII complex supported by π-radical
