  Preparation of silver nanoparticles from silver(I) nano-coordination polymer

  摘要：

  Nanorods of two-dimensional organometallic coordination polymer, [Ag(mu(4)-DPOAc)](n) (1) [DPOAc = diphenylacetate], has been synthesized by the reaction of potassium diphenylacetate (DPOAcK) and AgNO3 by sonochemical process. Reaction conditions, such as the concentration of the initial reagents played important roles in the size and growth process of the final product. Silver nanoparticles were synthesized from nanorods of compound 1. These nano-coordination polymer and nanoparticles were characterized by X-ray powder diffraction (XRD) and scanning electron microscopy (SEM). Thermal stability of nano and crystal samples of compound 1 were studied and compared with each other. (C) 2010 Elsevier B.V. All rights reserved.

  摘要：

  了解反应机制，尤其是手性诱导模式，对于开发新的不对称催化反应至关重要。铑 (III) 催化的 C-H 活化在与 α-重氮 β-酮酯进行阻转选择性 [4 + 2] 环偶联的过程中已经实现，提供了具有良好对映选择性的轴向手性菲。实验和计算研究的结合揭示了一种非传统的立体发散-收敛手性感应模式。反应以若达芴中间体进行，然后将两个 Rh-C（芳基）键竞争性、建设性和立体发散性迁移插入到卡宾物种中，得到 β-酮酯中间体。然后，另一个 Rh-C（芳基）键迁移插入到酮羰基中。2 )–C(sp 3 ) 手性轴生成。最终产品通过铑 (III) 物种的立体会聚消除而交付，同时保留了控制良好的轴向手性并失去了中心手性。

• Preparation and reactions of triarylsilylmethylmetallic reagents
  作者：A. G. Brook、J. M. Duff、D. G. Anderson

  日期：1970.2.15

  Triarylsilylmethylmetallic reagents have been prepared by several routes: metalation; addition of phenyllithium to vinyltriphenylsilane; direct synthesis; and by halogen–metal exchange. The latter method is highly superior as regards both generality of application and yields. Dibromomethylsilanes undergo halogen-metal exchange at −78°, and reaction of the product with hydrogen bromide serves as a valuable way of converting geminal dibromides to monobromides. The organometallic reagents have been characterized in several ways, in particular by carbonation to give the related carboxylic acid.

  三芳基硅甲基金属试剂已通过几种途径制备：金属化；苯基锂与乙烯三苯基硅烷的加成；直接合成；以及卤素金属交换。后一种方法在适用性和产率方面都具有极高的优势。二溴甲基硅烷在-78°下发生卤素金属交换，产物与氢溴酸的反应可作为将伪二溴化物转化为单溴化物的有价值途径。这些有机金属试剂已通过多种方式进行表征，特别是通过碳酸化得到相关的羧酸。

  these complexes contain P2AgO2 molecular cores with four-coordinate silver in which the carboxylate ligands are weakly bound to the silver atoms via the two oxygen atoms giving rise to unsymmetrical chelate units.

  Reaction of SbPh(2)Cl(3) (1 mol) with the silver salt of dicyclohexylphosphinic acid (2 mol) afforded SbPh(2)Cl[O2P(C6H11)(2)]}O-2 1, a similar reaction with AgO2P(C8H15)(2) gave a product formulated as SbPh(2)Cl[O2P(C8H15)(2)]}O-2 2. Similar reactions with silver carboxylates (1:3 stoichiometry) led to the crystalline derivatives [SbPh(2)(O(2)CR)(2)]O-2 (R = Ph 3, CHPh(2) 4, 2,4,6-Me(3)C(6)H(2) 5, 2-MeC(6)H(4) 6 or 4-MeC(6)H(4) 7), whereas the 1:2 reaction afforded crystalline SbPh(2)Cl(O(2)CR)(2) (R = Ph 8, 2-MeC(6)H(4) 9 or 4-MeC(6)H(4) 10). Interconversion of the previously known compounds [SbPh(2)(O(2)CMe)(2)]O and Sb(4)Ph(8)O(6) . 3MeCO(2)H was achieved and established by H-1 NMR spectroscopy. Compounds 1 and 3 were further characterized by X-ray diffraction; the antimony in 1 is six-co-ordinated with bridging phosphinates whereas in 3 it is seven-co-ordinated with chelating benzoates. Short Sb-O (oxo) distances (1.923 Angstrom) and near linearity at the bridging oxygen (Sb-O-Sb 173.9 degrees) are observed for 3.

• Unique Ag–C bonds, thermal, fluorescence, structural and solution studies of two-dimensional silver(I) coordination polymer
  作者：Kamran Akhbari、Ali Morsali、Matthias Zeller

  A 2D polymer with unique Ag-C bonds, [Ag(mu(4)-DPOAc)](n) (1) [DPOAc = diphenylacetate], has been synthesized and characterized and its structure was determined by X-ray crystallography. In addition to the coordination to the 0 atoms of DPOAc the Ag atoms also form strong eta(1) Ag-C pi bonds and exhibit weak Ag-Ag interactions, resulting in the formation of O3CAg... AgO3C moieties. The thermal stabilities of 1 and of its thallium(I) analogue, [Tl(mu(3)-DPOAc)](n) (2), were studied by thermal gravimetric (TG) and differential thermal analyses (DTA). The ligand and compounds 1-2 are luminescent in the solution state, with emission maxima at 370, 383 and 360 nm, respectively. The results of studies of the stoichiometry and formation of complexes of I and 2 in DMF solution were found to be in support of their solid state stoichiometry. (c) 2007 Elsevier B. V.
