  • Derivation of saddle shaped cyclooctatetrathiophene: increasing conjugation and fabricating pentamer
    作者:Yong Wang、Dewen Gao、Jianwu Shi、Yuhe Kan、Jinsheng Song、Chunli Li、Hua Wang

    日期:2014.1
    With cyclooctatetrathiophene (COTh) as building block, two alpha,alpha,alpha,alpha-tetraaryl COThs, COThP and COThTh have been efficiently synthesized. Phenyl and thienyl were employed as end-capping groups to introduce to COTh and increase its conjugation. For enlarging the special 'saddle' shaped structure, a pentamer of COTh was synthesized via Negishi reaction and CuCl2-promoted oxidative coupling reaction. The pentamer (COThF) is a new type of dendrimer with COTh as dendron, which presents an artistic configuration possessing a large saddle shape. All compounds were fully characterized by H-1 NMR, C-13 NMR, HRMS and IR. The crystal structures of COThP and COThTh were confirmed by X-ray analysis. The molecular configuration of COThF was optimized by theoretical calculations. Their UV-vis properties, electrochemical behaviours and thermo-gravimetric analysis of COThP, COThTh and COThF were also described. (C) 2013 Elsevier Ltd. All rights reserved.
  • Palladium‐Catalyzed Synthesis of Heteroarene‐Fused Cyclooctatetraenes through Dehydrogenative Cyclodimerization

    architectures. Considerable attention has been paid to the transition‐metal‐mediated synthesis of these cyclic compounds; however, there have been limited achievements to date in the efficient construction of heteroarene‐fused COTs. In this contribution, we report a novel Pd‐catalyzed dehydrogenative cyclodimerization of biheteroarenes through four‐fold C−H activation toward the synthesis of a series
    芳烃稠合的环辛酸酯(COT)具有独特的结构和电子特性,其源自鞍形π共轭体系。这些环状化合物的过渡金属介导的合成已引起相当大的关注。但是,迄今为止,在有效构建杂芳烃融合的COT方面取得的成就有限。在这项贡献中,我们报告了新型的Pd催化的双杂芳烃的脱氢环二聚反应,其通过四倍的CH活化作用来合成一系列杂芳烃融合的COT。一系列的机理研究表明,二价化事件之前,高价Pd物质参与了催化循环。还简要描述了获得的COT的氧化还原行为。
