    Examination of subsequent reaction products enhanced through parahydrogen-induced nuclear polarization (PHIP)
    摘要:
    Homogeneous hydrogenation with parahydrogen yields strong nuclear spin polarization in the H-1 NMR spectra of the reaction products. This polarization can be transferred to subsequent reaction products and detected by in situ H-1 MMR spectroscopy. As a typical example, the hydrogenation of 1-phenylpropyne with parahydrogen generates the spin-polarized molecule 1-phenylpropene. Upon bromination of this product, its polarization is transferred to the reaction product 1,a-dibromo-l-phenylpropane. As a second example, polarization was observed in the addition product of DBr to spin-polarized dimethyl maleate which is generated from dimethyl acetylenedicarboxylate by addition of parahydrogen.

    费歇尔卡宾配合物与炔烃反应的间苯并环化的第一个例子
    摘要:
    检查卡宾配合物与炔烃的分子内苯环化,其中炔烃系在乙烯基卡宾配合物的α-碳上。这些反应对系绳的长度和溶剂的性质很敏感。系链长度为 16 亚甲基时,反应以与分子间反应相同的方式发生,得到对环烷。对于中间系链长度 (n = 10, 13),该反应产生了一个额外的对环芳,其中两个氧取代基在芳烃环上是间位的。这种类型的产品是前所未有的卡宾配合物和炔烃的反应,并且非常令人惊讶,因为这种产品的形成需要乙烯基卡宾配合物的 α-和β-碳之间的碳-碳键被破坏。

The connectivity patterns of the bridges in the cyclophanes can be controlled by regioselectivity transfer from the bis‐vinyl carbene complexes in which the substitution pattern of the vinyl groups in the carbene complexes dictate the connectivity pattern in the [m.n]cyclophanes. This synthesis of [n.n]cyclophanes is quite flexible with regard to ring size and can be used with tether

  • The First Examples of a <i>Meta</i>-Benzannulation from the Reaction of Fischer Carbene Complexes with Alkynes

    日期:2003.7.1
    intramolecular benzannulations of carbene complexes with alkynes are examined where the alkyne is tethered to the alpha-carbon of the vinyl carbene complex. These reactions are sensitive to the length of the tether and to the nature of the solvent. With a tether length of 16 methylenes, the reaction occurs in the same fashion as the intermolecular reactions to give a p-cyclophane. With intermediate
