  • Cyclisation of acetylenic carboxylic acids and acetylenic alcohols to oxygen-containing heterocycles using cationic rhodium(I) complexes
    作者:Sarah Elgafi、Leslie D Field*、Barbara A Messerle*
    DOI:10.1016/s0022-328x(00)00233-3
    日期:2000.8
    [mim=N-methylimidazol-2-yl, mBnzim=N-methylbenzimidazol-2-yl] are catalysts for the cyclisation of alkynoic acids to lactones. The unsaturated acids, 4-pentynoic acid, 4-hexynoic acid and 5-hexynoic acid were cyclised to γ-methylene-γ-butyrolactone, E-5-ethylidenetetrahydro-2-furanone and 6-methylidenetetrahydo-2-pyrone, respectively. Cyclisation of 4-hexynoic acid proceeds stereoselectively with exclusive formation
    方形平面阳离子铑(I)二羰基配合物[Rh((mim)2 CH 2)(CO)2 } + BPh 4 - ](1)和[Rh((mbnzim)2 CH 2)(CO)2 } + BPh 4 - ](2)[mim =N-甲基咪唑-2-基,mBnzim =N-甲基苯并咪唑-2-基]是用于将炔酸环化成内酯的催化剂。将不饱和酸4-戊酸,4-己酸和5-己酸环化为γ-亚甲基-γ-丁内酯E.-5-亚乙基四氢-2-呋喃酮和6-亚甲基四氢-2-吡喃酮。4-己酸的环化立体选择性地进行,唯一形成了5-亚乙基四氢-2-呋喃酮的E-异构体。配合物1和2还催化炔属醇环化成含氧杂环。
  • Silver-zeolite catalysed solvent free synthesis of (spiro)ketals

    were able to catalyse, without solvents and at low silver loading, the formation of (spiro)ketals from alkyn(edi)ols. Such Ag-zeolite catalysts could be recycled without any activity loss. This study constitutes the first (spiro)ketalization mediated by silver heterogeneous catalysts, but also a truly ‘green’ (spiro)ketalization.

  • A Metal–Organic Framework with Cooperative Phosphines That Permit Post‐Synthetic Installation of Open Metal Sites

    PCM‐101 is a phosphine coordination material comprised of tris(p‐carboxylato)triphenylphosphine and secondary pillaring groups coordinated to [M3(OH)]5+ nodes (M=Co, Ni). PCM‐101 has a unique topology in which R3P: sites are arranged directly trans to one another, with a P⋅⋅⋅P separation distance dictated by the pillars. Postsynthetic coordination of soft metals to the P: sites proceeds at room temperature
    PCM-101是一种膦配位材料,由三(对羧基羧基)三苯基膦和与[M 3(OH)] 5+节点(M = Co,Ni)配位的第二级支柱基团组成。PCM-101具有独特的拓扑结构,其中R 3P:位点彼此直接成直角排列,柱子之间的间距为P⋅⋅⋅P。在室温下,软金属与P:位的合成后配位会进行,以提供X射线质量的晶体,从而具有完整的结构分辨率。AuCl基团的加入迫使母体框架发生很大的变形。相比之下,CuBr直接在反式-P位点之间插入以形成模拟溶液相复合物的二聚体,但由于MOF支架施加的空间压力而在几何上受到拉紧。在温和条件下,金属化材料在非均相加氢催化中具有活性,与它们的分子对应物相比,可产生不同的主要产物。

  • Conversion of pentynol to pentanone catalysed by Pd(II) metal centres
    作者:M. Fernanda N.N. Carvalho、Ana S.D. Ferreira、Rudolf Herrmann
    DOI:10.1016/j.jorganchem.2006.06.022
    日期:2006.9
    The cyclization of 3- or 4-pentyn-1-ol is catalysed by PdCl2 or trans-[PdCl2L2] (L = R-camphorimine; R = Ph; Pr-i; NMe2) complexes at room temperature affording heterocyclic compounds, respectively, 2-methyl-2-pent-3-ynyloxy-tetrahydrofuran or 2-methyl-2-pent-4-ynyloxy-tetrahydrofuran which subsequently add water to give selectively 5-(2-methyl-tetrahydrofuran-2-yloxy)-pentan-2-one from both starting materials. By hydrolysis 5-(2-methyl-tetrahydrofuran-2-yloxy)-pentan-2-one undergoes ring cleavage to form 5-hydroxy-2-pentanone. The catalytic activity and selectivity of complexes trans-[PdCl2L2] (L = R-camphorimine) depend on the characteristics of the R group (NMe2 > Pr-i > Ph). The catalytic activity of PdCl2 is comparable to that of trans-[PdCl2L2] (L = Ph-camphorimine) which is the less efficient catalyst. (c) 2006 Elsevier B.V. All rights reserved.
