    Thermodynamic Control of Isomerizations of Bicyclic Radicals: Interplay of Ring Strain and Radical Stabilization
    摘要:
    The rearrangements of 4-substituted bicydo[2.2.2]oct-5-en-2-yl radicals, generated from the corresponding Die Is Alder adducts with phenylseleno acrylates by radical-induced reductive deselenocarbonylations, give the 2-substituted bicydo[3.2.1]oct-6-en-2-yl radicals with some substituents, e.g., alkoxy and phenyl, but not for silyloxymethyl or benzyl substituents. Theoretical calculations with DFT give the thermodynamics of these reactions and the origins of these processes.

  • Carbopalladation of Nitriles:  Synthesis of 2,3-Diarylindenones and Polycyclic Aromatic Ketones by the Pd-Catalyzed Annulation of Alkynes and Bicyclic Alkenes by 2-Iodoarenenitriles
    作者:Alexandre A. Pletnev、Qingping Tian、Richard C. Larock
    DOI:10.1021/jo026178g
    日期:2002.12.1
    represents one of the first examples of the addition of an organopalladium moiety to the carbon-nitrogen triple bond of a nitrile. The reaction is compatible with a number of functional groups. A reaction mechanism, as well as a model accounting for the electronic effects of substituents on the aromatic ring of the nitrile, is proposed.
    2-碘苄腈,其衍生物和各种杂环类似物在二芳基乙炔或双环烯烃上进行钯(0)催化的环化反应,从而以非常好的至极好的收率得到2,3-二芳基萘和多环芳族酮。该反应代表将有机钯部分加成到腈的碳-氮三键上的第一个例子。该反应与许多官能团相容。提出了反应机理以及考虑取代基对腈芳环电子效应的模型。
  • The Reaction of Difluorocarbene with Bicyclo[2.2.2]octadiene
    作者:Charles W. Jefford、Arlette Delay、Timothy W. Wallace、Ulrich Burger
    DOI:10.1002/hlca.19760590708
    日期:1976.11.3
    The addition of difluorocarbene to bicyclo[2.2.2]octa-2,5-diene gave the exo and endo 1:1 cyclopropane adducts. In contrast to norbornadiene, no homo-1,4 adduct was formed. The adducts were thermally stable under the conditions of their formation and separation (<170°). However, smooth equilibration was achieved on heating at 250° for 36 h. The same mixture resulted from either isomer. At 250° ΔΔG
    将二氟卡宾加至双环[2.2.2] octa-2,5-二烯中,可得到外向和内向1:1的环丙烷加合物。与降冰片二烯相反,没有形成均一的-1,4加合物。加合物在其形成和分离(<170°)的条件下是热稳定的。但是,在250°C加热36小时后,达到了平稳的平衡。两种异构体均产生相同的混合物。在250℃ΔΔ ģ = 1.83千卡/摩尔; 该内异构体是更稳定。加热到更高的温度会引起分解,而不是进一步与分子内[2 + 2]环化产物发生反应。在外推至相同温度时,动力学和热力学产物组成基本相同。内/外25°时19-22。讨论了顺式稠合的环丙烷部分的环加成和立体突变发生的机理。

    Catalytic one-pot reactions of aromatic iodides with alkyl halides, phenylacetylene or diphenylacetylene, potassium acetate or carbonate, norbornene and palladium acetate in DMF or DMA are reported. A high selectivity towards dialkylsubstituted diarylacetylenes and diarylalkylidenehexahydromethanofluorenes, respectively, has been reached.

  • Palladium-catalyzed heteroannulation of cyclic alkenes by functionally substituted aryl iodides
    作者:Daniel E. Emrich、Richard C. Larock

    日期:2004.11
    heteroannulation of cyclic and bicyclic alkenes by o-amino- and o-hydroxyaryl iodides. These processes are only successful with cyclic olefins in which the key alkylpalladium intermediate cannot undergo facile palladium β-hydride elimination. These reactions appear to involve: (1) oxidative addition of the aryl iodide to the palladium catalyst, (2) arylpalladation of the olefin, (3) possible coordination

  • The β-effect of silicon in the orthogonal geometry
    作者:Joseph B. Lambert、Xiaoyang Liu
    DOI:10.1016/0022-328x(96)06228-6
    日期:1996.8
    β-effect of silicon has been investigated through the preparation of 1-(trimethylsilyl)bicyclo[2.2.2]octan-2-ol (5-OH) and its sulfonate derivatives. The dihedral relationship in 5 between the trimethylsilyl group and the bond to the leaving group approaches orthogonality, preventing any contribution to the β-effect from either hyperconjugation or bridging. Any residual effect of silicon should come
    已经通过制备1-(三甲基甲硅烷基)双环[2.2.2]辛-2-醇(5-OH)及其磺酸酯衍生物研究了对硅的β效应的感应贡献。三甲基甲硅烷基与离去基团的键之间5的二面关系接近正交,从而防止了超共轭或桥连对β效应的任何贡献。硅的任何残留效应都应来自感应。与无硅模型双环[2.2.2]辛-2-基甲苯磺酸酯(7-OTs)相比,甲苯磺酸酯的比率在80-97%的三氟乙醇水溶液中于20-72%时为1.2-1.3。 35℃。这种微不足道的β效应与在近平面上的几何值大约为10 5,在渐近几何上的近似值为10 4以及在10 12上近似为10 12。在反平面几何形状处。完全的二面角依赖性类似于超共轭机制而不是桥接所期望的余弦平方曲线,归纳贡献很小。
