  • Hydrogen/Halogen Exchange of Phosphines for the Rapid Formation of Cyclopolyphosphines
    作者:Adam N. Barrett、Callum R. Woof、Christopher A. Goult、Danila Gasperini、Mary F. Mahon、Ruth L. Webster
    DOI:10.1021/acs.inorgchem.1c02734
    日期:2021.11.1
    The hydrogen/halogen exchange of phosphines has been exploited to establish a truly useable substrate scope and straightforward methodology for the formation of cyclopolyphosphines. Starting from a single dichlorophosphine, a sacrificial proton “donor phosphine” makes the rapid, mild synthesis of cyclopolyphosphines possible: reactions are complete within 10 min at room temperature. Novel (aryl)cyclopentaphosphines
    膦的氢/卤素交换已被用于建立真正可用的底物范围和形成环多膦的直接方法。从单一的二氯膦开始,牺牲质子“供体膦”使环多膦的快速、温和合成成为可能:反应在室温下 10 分钟内完成。新的(芳基)环五膦(ArP)5已经以良好的转化率形成,并具有晶体结构。在二膦 (Ar 2 P) 2和烷基取代的环四或环五膦((AlkylP) n,其中n= 4 或 5) 形成。无铁和铁介导的反应都对一种特定的环尺寸显示出高水平的选择性。最后,对 Fe(acac) 3反应性的研究表明,铁物质充当了反应副产物盐酸的汇。
  • Catalytic Enantioselective Hydrosilylation of Aromatic Ketones Using Rhodium Complexes of TADDOL-Derived Cyclic Phosphonites and Phosphites

    phosphites 2–4 are readily available from Cl2PR and (R,R)- or (S,S)-α,α,α′,α-tetraaryl-1,3-dioxolane-4,5-dimethanols (= TADDOLs 1, which, in turn, are only two steps away from tartrate); the X-ray crystal structure of one representative, the phenyl phosphonite 2b, was determined. Five previously described and six new ones of the chiral P derivatives were tested as ligands for RhI- and PdO-catalyzed reactions

  • Convenient and Scalable Synthesis of Aryldichlorophosphines and Primary Arylphosphines via Perthiophosphonic Anhydrides
    作者:Petr Kilian、Daniel Picthall、Brian A. Surgenor
    DOI:10.1055/a-1994-2301
    日期:2023.3
    scalable synthetic route to both primary arylphosphines ArPH2 and aryldichlorophosphines ArPCl2 is reported. The C–P bond formation was performed in a highly regiospecific manner through electrophilic substitution of selected aromatic hydrocarbons (ArH) with phosphorus pentasulfide. The resultant perthiophosphonic anhydrides Ar2P2S4 were then reacted with LiAlH4 to give primary phosphines ArPH2. Subsequent
