  • Intermolecular On-Surface σ-Bond Metathesis

    self-assembly structures to be generated from molecules that are inherently unstable in solution and in the solid state. This is shown by the successful formation of self-assembled hexaethynylbenzene at Ag(111). Furthermore, it is also shown that on the Au(111) surface this σ-bond metathesis can be combined with Glaser coupling to fabricate covalent polymers via a cascade process.
    甲硅烷基化和甲硅烷基化是溶液相有机化学中重要的官能团操作,其被大量用于保护/脱保护不同的官能团。在这里,我们公开了在Ag(111)和Au(111)表面上与芳族羧酸进行甲硅烷基化炔烃的σ键复分解的第一个实例,从而给出了相应的末端炔烃和甲硅烷基酯,这在密度泛函理论计算的支持下得以实现。并通过X射线光电子能谱分析进一步证实。应用于表面化学的这种保护基策略允许从在溶液和固态中固有地不稳定的分子产生自组装结构。这可以通过在Ag(111)上成功形成自组装的六乙炔基苯来证明。此外,

  • Transition-Metal-Free Synthesis of Conjugated Polymers from Bis-Grignard Reagents by Using TEMPO as Oxidant

    日期:2010.5.25
    Increasing the TEMPO! Transition metals are not necessary for oxidative polymerization of 2,7‐di‐magnesated fluorenes. Oxidation readily occurs by using the commercially available 2,2,6,6‐tetramethyl‐piperine 1‐oxyl radical (TEMPO) as an oxidant. Polyfluorenes with Mn of up to 9000 g mol−1 can be obtained (see scheme).
    增加速度!过渡金属对于2,7-双放大的芴的氧化聚合不是必需的。使用市售的2,2,6,6-四甲基胡椒碱1-氧基(TEMPO)作为氧化剂很容易发生氧化。可以得到M n高达9000 g mol -1的聚芴(参见方案)。
  • Macrocyclic Cyclophanes with Two and Three α,ω-Dichalcogena-1,4-diethynylaryl Units: Syntheses and Structural Properties
    作者:Daniel B. Werz、Felix R. Fischer、Stefan C. Kornmayer、Frank Rominger、Rolf Gleiter

    日期:2008.10.17
    By means of four- and six-component cyclization reaction various cyclophanes were synthesized. The components were the di(lithium) salts of 1,4-di(ethynyl)benzene (11), 4,4'-di(ethynyl)biphenyl (13), 1,4-di(ethynyl)-2,5-di(n-hexyl)benzene (18), and 1,4-di(ethynyl)-2,5-di(n-propyl)benzene (19). These building blocks were reacted with alpha,omega-dithiocyanato-n-alkanes and alpha,omega-diselenocyanato-n-alkanes with n = 3-6. In the case of 10 also 1,1'-di(2-thiocyanatoethyl)cyclohexane (24) was reacted to afford a cyclophane comprising three subunits of 11. From most of the resulting macrocyclic cyclophanes (4(n) (n = 3, 5), 5, 6, 7(n), 8(n) (n = 3-6), 9(n) (n = 3, 5), and 10), we were able to grow single crystals. The X-ray analysis of 4(3), 7(3), 8(3), 8(4), 6, 7(5), and 8(5) revealed close contacts between the chalcogen atoms. These chalcogen-chalcogen interactions impose a ribbon-shape arrangement of molecules in 4(3) and a mutual crossing of two perdendicular planes built of 8(4) molecules. For 4(3) we found a close contact (3.28 angstrom) between the pi planes of two neighboring C6H4 rings of different molecules, whereas in 8(4) such a close contact (3.74 angstrom) was due to an intermolecular interaction. Tubular stacking of the macrocyclic rings was found for 7(5) and 8(5) caused by a ladder-type intermolecular chalcogen-chalcogen interaction.
