    Biaryl阳离子自由基中从静态孔离域到动态跳跃的二面角控制交叉
    摘要:
    在联芳基化合物具有相干电荷转移机制的情况下,速率遵循具有二面角变化的余弦平方趋势。在本文中,我们证明了使用一系列具有不同二面角的联芳基阳离子自由基,空穴稳定化显示了两个不同的状态,其中空穴稳定化的机理从两个芳基环上的(静态)离域转换为(动态)跳跃。具有不同二面角的联芳烃的实验数据和DFT计算明确支持从离域到跳跃的交换发生在唯一的二面角处,其中电子耦合(H ab)是重组(λ)的一半,即H ab = λ/ 2。目前正在研究这一发现对非相干电荷传输速率的影响。

  • An economical and environmentally friendly oxidative biaryl coupling promoted by activated MnO<sub>2</sub>

    DOI:10.1039/c4ob01409j
    日期:——
    An activated manganese dioxide (MnO2)–BF3·OEt2 oxidation system was developed to efficiently mediate the intramolecular as well as intermolecular biaryl coupling. The oxidative coupling proceeds smoothly at ambient temperature to deliver the corresponding five- to eight-membered tricyclic products in good to excellent yields. The employment of the combination of MnO2 and BF3·OEt2 is attractive on the basis of economical and environmental issues.
    开发了一种活化的二氧化锰(MnO2)–BF3·OEt2氧化系统,能够高效地介导分子内和分子间的二芳基偶联。该氧化偶联在常温下顺利进行,产物为相应的五到八元环三环化合物,产率良好至优秀。基于经济和环境问题,使用MnO2和BF3·OEt2的组合具有吸引力。
  • Seven- and eight-membered heterocyclic biaryl synthesis through a metal-free oxidative coupling reaction

    A metal-free intramolecular biaryl coupling mediated by DDQ and BF3 center dot OEt2 was developed. The reaction proceeds smoothly at room temperature to give seven- and eight-membered heterocyclic biaryl compounds in up to 95% yields. Only 1 equiv of DDQ sufficed for the reaction, obviating the use of a large excess of oxidants and undesired chlorination pathway in metal-mediated process. (C) 2014 Elsevier Ltd.

    and powerful active anode system that can be operated in 1,1,1,3,3,3‐hexafluoro‐2‐propanol (HFIP) has been discovered. In HFIP the molybdenum anode forms a compact, conductive, and electroactive layer of higher‐valent molybdenum species. This system can replace powerful but stoichiometrically required MoV reagents for the dehydrogenative coupling of aryls. This electrolytic reaction is more sustainable
