  • Complexes of long alkyl chain tertiary phosphines. Part I. The preparation and characterization of platinum metal complexes of long-chain tertiary phosphine ligands
    作者:S. Franks、F.R. Hartley
    DOI:10.1016/s0020-1693(00)89336-6
    日期:1981.1
    Abstract The long chain tertiary phosphine ligands (P(CnH2n+1)3 and P CmH2m·1)3 have been used to prepare the following series of platinum, palladium and rhodium complexes: cis-[PtL2Cl2], trans-[PdL2Cl2], trans-[PtL2HCl] (L = trialkylphosphine only), [PtL4] and trans-[RhL2Cl(CO)]. The complexes are very soluble in chlorinated solvents and both aliphatic and aromatic hydrocarbons as well as tetrahydrofuran
    摘要长链叔膦配体(P(CnH2n + 1)3和P CmH2m·1)3已用于制备以下系列的铂,钯和铑配合物:顺式[PtL2Cl2],反式[PdL2Cl2],反式-[PtL2HCl](仅L =三烷基膦),[PtL4]和反式-[RhL2Cl(CO)]。该络合物在氯化溶剂,脂族和芳族烃以及四氢呋喃中都非常易溶,但不溶于或仅微溶于极性溶剂(如醇,丙酮和二乙醚)中。许多配合物是结晶固体,其纯化仅需小心。但是,必须格外小心地选择许多蜡或油,以及所用的制备路线和后处理程序。

    A composition comprising a supported hydrogenation catalyst comprising palladium and an organophosphorous compound, the supported hydrogenation catalyst being capable of selectively hydrogenating highly unsaturated hydrocarbons to unsaturated hydrocarbons. A method of making a selective hydrogenation catalyst comprising contacting a support with a palladium-containing compound to form a palladium supported composition, contacting the palladium supported composition with an organophosphorus compound to form a catalyst precursor, and reducing the catalyst precursor to form the catalyst. A method of selectively hydrogenating highly unsaturated hydrocarbons to an unsaturated hydrocarbon enriched composition comprising contacting a supported catalyst comprising palladium and an organophosphorous compound with a feed comprising highly unsaturated hydrocarbon under conditions suitable for hydrogenating at least a portion of the highly unsaturated hydrocarbon feed to form the unsaturated hydrocarbon enriched composition.

    of the ionic planes (where the phosphonium cationic centers and anions are located) that separate the layers are antiparallel. In each molecule, two of the long n-alkyl chains are paired while the third is antiparallel to the other two and paired with an n-alkyl chain of a molecule in a neighboring bilayer. The tri-n-alkylmethylphosphonium salts (1PnX) with small anions X (where n = 6−18 is the number

  • Smectic Liquid-Crystalline Phases of Quaternary Group VA (Especially Phosphonium) Salts with Three Equivalent Long <i>n</i>-Alkyl Chains. How Do Layered Assemblies Form in Liquid-Crystalline and Crystalline Phases?
    作者:David J. Abdallah、Allan Robertson、Hsiu-Fu Hsu、Richard G. Weiss
    DOI:10.1021/ja994055g
    日期:2000.4.1
    The neat phase behavior of 28 phosphonium salts (nPmA), each with three equivalent long n-alkyl chains containing m carbon atoms and one shorter chain containing n carbon atoms or a benzyl group, have been examined. Eighteen form a liquid-crystalline smectic A2 (SmA2) phase, where the lipophilic chains assemble in bilayers that sandwich an “ionic plane” consisting of an array of anions and positively
    已经检查了 28 种鏻盐 (nPmA) 的纯相行为,每种盐都有三个等效的长 n-烷基链,包含 m 个碳原子,一个较短的链包含 n 个碳原子或一个苄基。十八个形成液晶近晶 A2 (SmA2) 相,其中亲脂性链组装成双层,夹着一个“离子平面”,该“离子平面”由一系列阴离子和带正电荷的磷原子组成。也检测了几种类似的铵盐。这些是首次报道的液晶两亲物结构,其中包含三个等效的长正烷基链和一个单原子头基。此外,nPmA 展示了当链的横截面积远大于头基的横截面积时,亲脂链的空间相互作用和离子部分之间的静电相互作用必须如何在分层组件中平衡。提出了一个模型来解释 nPmA 液晶相中层厚度对 m、n、...的依赖性。
