  Nickel(II) complexes with bifunctional phosphine–imidazolium ligands and their catalytic activity in the Kumada–Corriu coupling reaction

  摘要：

  Zwitterionic Ni(II) complexes of type NiX3(NCN+), (NCN+ = 1-(2-diphenylphosphinoethyl)-3-(2,4,6-trimethylphenyl)imidazolium and X = Cl, 6; Br, 7), have been prepared by addition of NCN+ bromide (1a) or tetrafluoroborate (1b) to NiX2L, and characterised by X-ray crystallography. They have been used as catalytic precursors in the Kumada-Corriu coupling reaction between phenylmagnesium chloride and 4-chloroanisole, yielding high catalytic activities. Stoechiometric deprotonation investigations did not provide clear evidence for the formation of coordinated carbene species. (c) 2005 Elsevier B.V. All rights reserved.

  In this account the authors' latest results in C-C coupling catalysis are reviewed. First, an efficient catalytic system for the Kumada-Tamao-Corriu coupling reaction based on NHC-phosphine (NHC = N-heterocyclic carbene) nickel complexes is presented. Then the use of palladium complexes of chiral ferrocenyl NHC-phosphines in the asymmetric Suzuki-Miyaura coupling reaction is reported. High catalytic activities and moderate enantioselectivities (ee up to 46%) were obtained. Chiral ferrocenyl phosphine-ethers were also tested in the asymmetric Suzuki-Miyaura reaction yielding good activities and moderate enantioselectivities (ee up to 37%). Finally, the original synthesis of a ferrocenyl rhodium(III) complex and its successful use as catalyst for a C-C coupling reaction via C-H activation of 2-phenylpyridine is presented.

  在这篇报道中，作者回顾了他们在C-C偶联催化方面的最新成果。首先，介绍了一种基于NHC-膦（NHC = N-杂环卡宾）镍复合物的高效催化体系，用于Kumada-Tamao-Corriu偶联反应。然后，报告了手性二茂铁NHC-膦的钯复合物在不对称Suzuki-Miyaura偶联反应中的应用，获得了高催化活性和适中的对映选择性（对映体富集率高达46%）。手性二茂铁膦醚在不对称Suzuki-Miyaura反应中也进行了测试，表现出良好的催化活性和适中的对映选择性（对映体富集率高达37%）。最后，介绍了一种二茂铁铑(III)复合物的原创合成及其成功作为催化剂通过C-H活化2-苯基吡啶进行C-C偶联反应的应用。
