  取代基对二噻吩基吡咯自由基阳离子的结构，稳定性和π-二聚化的影响

  摘要：

  合成了一系列在噻吩环的3-位带有甲硫基封端基团和给电子取代基的2,5-二（2-噻吩基）-N-甲基吡咯衍生物1a - 1d，并且这些取代基的作用使用UV-vis-NIR和电子自旋共振谱以及密度泛函理论（DFT）计算研究了自由基阳离子的结构，稳定性和π-二聚能力。在供电子的甲基，甲氧基和甲硫基取代基中，甲氧基衍生物1c给出了最稳定的自由基阳离子，该阳离子在室温，氮气下于二氯甲烷中持续存在数小时，而没有任何明显的分解。另外，1c •+在1a •+ – 1d •+中具有最大的π二聚焓。DFT计算与M06-2X方法揭示，甲基和甲硫基衍生物1B •+和1D •+以及1C •+采取顺-顺式构象，相对于未取代的反式-反构象异构体1A •+ ，而所有这些化合物的π-二聚体均显示具有顺式-顺式构象。在进一步详细分析的基础上，考虑了预先形成的顺式-顺式构象以及较弱的分子内和分子间空间排斥力，以解释为什么1c •+

  The Knorr-Paal reaction of 1,4-di(2-thienyl)-1,4-butanedione with anilines to yield N-substituted-2,5-di-(2-thienyl)-1H-pyrroles (SNS derivatives) was tested by using different acid catalysts in toluene and acetic acid. Di-SNS derivatives were also synthesized in toluene at reflux in the presence of propionic acid, these mild conditions giving acceptable yields in a one-step procedure. (C) 2002 Elsevier Science Ltd.
