  The ionic mononuclear and trinuclear Au(I)-complexes ligated by phosphine-functionalized ionic liquids: Synthesis, characterization, and catalysis to hydration of phenylacetylene

  摘要：

  A series of ionic Au(I)-complexes ligated by the phosphine-functionalized ionic liquids were synthesized and characterized, which are composed of the Au(I)-complex cation and the counteranion of OTf , AuCl4, or PF6-, respectively. The single crystal X-ray diffraction analyses show that the Au(I)-centered vector in 1A, 1B, 2A, 3A, and 4A all possess the slightly twisted linear geometry, and in each individual the Au(I)-center is coordinated by one chlorine and one imidazolium-based phosphine. The aggregation of 1B in acetone can lead to the formation of the trinuclear Au(I)-complex of 1C due to the aurophilic Au(I)-Au(I) interaction, the electrostatic attraction, and the steric preference. When these ionic Au-complexes were employed as precatalysts for hydration of phenylacetylene in aqueous-methanol media, the reaction proceeded selectively according to Markovnikov's rule with moderate to high yields of acetophenone. The highest activities were achieved over 2A with hydrophobic PF6- as the counteranion and the trinuclear 1C under mild conditions (75 degrees C, 2 h), in conjunction with the additive of proton acid H2SO4. The ion-pair effect on the catalytic performance of the corresponding Au(I)-complexes, coming from the phosphine-ligated cations and the counteranions, were investigated. (C) 2014 Elsevier B. V.

  Fused in the same molecule! An N‐heterocyclic carbene and a diphosphine are generated and used in the modular synthesis of a variety of target heterometallic complexes. The experimental approach involves formation of a unique 4,5‐bis(diphenylphosphino)‐1,3‐dimethyl‐imidazolium salt, simply by starting from 1‐methylimidazole (see scheme; M1=Cr, Mn; M2=Au, Rh, Pd; LiHMDS=LiN(SiMe3)2).

  We report that treatment of several 2‐diphenylphosphinoimidazoles with Pd(II) salts generates monosubstituted N−H NHC−Pd complexes via insertion into the C−P bond. Removal of the N−H proton in situ leads to anionic (X‐type) or imidazolyl‐Pd complexes that are highly stable and catalytically active, achieving up to 340,000 turnovers at 1 ppm catalyst loading in Suzuki‐Miyaura reactions. DFT‐calculated

  我们报告说，用Pd（II）盐处理几种2-diphenylphosphinoimidazoles会通过插入CP键生成单取代的NH NHC-Pd复合物。原位除去NH质子会生成高度稳定且具有催化活性的阴离子（X型）或咪唑基-Pd络合物，在Suzuki-Miyaura反应中，当催化剂负载1 ppm时，可实现高达340,000的周转率。DFT计算的空间小的配体的Tolman电子参数表明，这些配体比传统的NHC显着增加了供体，这为快速交叉偶联催化提供了理论依据。Sonogashira反应中也显示出优异的反应性。
