  寡（2-甲氧基-5-（2'-乙基己氧基）-1,4-亚苯基亚乙烯基）中的受控区域规则性

  摘要：

  一系列的2-甲氧基-5-（2'-乙基己氧基）五聚体3个衍生物的- p -phenylenevinylenes（2 - 4），具有不同程度的侧链区域规则性，制备。使用具有四个不同取代基的精确取代的芳基环的重复Horner-Wadsworth-Emmons（HWE）反应进行低聚化学反应。通过溶液和薄膜中的核磁共振波谱（NMR），循环伏安法（CV）和吸收波谱对所得的低聚物进行表征。每个低聚物给出不连续的1 H和13 C NMR光谱。区域规则的五聚体（2）在信号之间显示出最高分辨率，表明这些核比区域随机五聚体（3和4）驻留在更独特的化学环境中。发现每种新的低聚物的溶液相电子（CV）和吸收性质基本相同。相反，薄膜吸收光谱不相等。区域规则性更强的五聚体（2和3）具有新的红移的肩部结构，这表明即使在五聚体水平上，堆积顺序也受到侧链区域规则性的严重影响。

• A Unified Approach to Couple Aromatic Heteronucleophiles to Azines and Pharmaceuticals
  作者：Ryan G. Anderson、Brianna M. Jett、Andrew McNally

  DOI：10.1002/anie.201807322

  日期：2018.9.17

  Coupling aromatic heteronucleophiles to arenes is a common way to assemble drug‐like molecules. Many methods operate via nucleophiles intercepting organometallic intermediates, via Pd‐, Cu‐, and Ni‐catalysis, that facilitate carbon‐heteroatom bond formation and a variety of protocols. We present an alternative, unified strategy where phosphonium salts can replicate the behavior of organometallic intermediates

  将芳香族异核试剂与芳烃偶联是组装类药物分子的常见方法。许多方法通过亲核试剂拦截有机金属中间体，通过 Pd、Cu 和 Ni 催化来进行，从而促进碳杂原子键的形成和各种方案。我们提出了一种替代的、统一的策略，其中鏻盐可以复制有机金属中间体的行为。在一组狭窄的反应条件下，多种芳香族杂核亲核试剂可以与吡啶和二嗪偶联，这在金属催化偶联中经常出现问题，例如在具有多个极性官能团的复杂结构中无法获得（假）卤化物前体。
