    摘要:
    一系列具有吡啶功能化N-杂环卡宾不同取代基的钯配合物被合成出来。通过X射线衍射研究确定了一些选定配合物的分子结构,显示出具有围绕钯中心的卡宾、吡啶和两个氯化物配体的伪平面四方结构。研究了不同取代基对配合物结构和反应性的影响。这些配合物的催化性质在Mizoroki-Heck反应中进行了研究,用于溴苯与各种芳基卤化物的交叉偶联。它们在这些反应中的性能各异,但表现出良好的产物区域选择性。

    摘要:
    摘要 DeC 活化的炔烃如二叔丁基乙炔二羧酸酯 (DTA) 或反应性更强的二甲基乙炔二羧酸酯 (DMA) 不与带有异双位碳烯-吡啶 (C- N) 作为旁观配体得到相应的乙烯基衍生物。为了制备这种类型的衍生物,我们采用了一种专门的合成方案,该方案基于用卡宾 - 吡啶氯化银配合物的卡宾 - 吡啶配体置换乙烯基钯吡啶 - 硫醚物种的不稳定吡啶 - 硫醚配体。然而,通过这种合成方案获得的新型卡宾 - 吡啶乙烯基配合物,如果与具有类似空间要求的其他钯乙烯基物种相比,显示出与乙炔基 - 锡烷的金属转移反应显着降低的反应性。

  • Tunable iridium catalyst designs with bidentate N-heterocyclic carbene ligands for SABRE hyperpolarization of sterically hindered substrates
    作者:Pierce Pham、Christian Hilty

    A series of bidentate N-heterocyclic carbene (NHC) iridium catalysts, [Ir(κC,N-NHC)H2L2]BPh4, are proposed for SABRE hyperpolarization. The steric and electronic properties of the NHCs are used to tune substrate affinity and thereby SABRE efficiency. The sterically hindered substrates 2,4-diaminopyrimidine and trimethoprim yielded maximum proton NMR signal enhancements of ∼300-fold and ∼150-fold, respectively

  • Cationic Gold Catalysis with Pyridine-Tethered Au(III) NHC-Carbenes: An Experimental and DFT Computational Study
    作者:Mikko Muuronen、Jesus E. Perea-Buceta、Martin Nieger、Michael Patzschke、Juho Helaja
    DOI:10.1021/om3003027
    日期:2012.6.11
    A novel strategy is developed to produce catalytically active cationic Au(III) species by pyridine-tethered NHC complexes. The catalytic properties of two NHC complexes, equipped with distinct pyridine moieties, were studied for two catalytic benchmark reactions, the cycloisomerization of alkynylfurans to isobenzofuranoles and o-alkynylanilines to indoles. Optimal catalytic results were obtained employing a complex tethered with an electron-rich, p-methoxy-substituted pyridine. The catalysis showed high selectivity, yielding clean product conversions, while the catalytic TONs achieved in the studied reactions are well comparable with the ones reported in the literature for silver salt-activated Au(I) NHC carbene catalysts. Computational results at the DFT level support the hypothesis that equilibrating ionic complexes are the plausible catalytically active species. Computational inspection of the energetics and molecular orbital involved in the reaction reveals that the ionic state is more favored in the AuCl3NHC complex equipped with the electron-rich pyridine.
