that the triphenylarsine ligand can accelerate the reaction rate of Stille coupling. However, other arsine ligands have never been investigated for the Stille coupling reaction so far. In this work, we prepared 13 kinds of C3-symmetrical tertiary arsine ligands and discovered that tri(p-anisyl)arsine is the best ligand for the reaction of tributylvinyltin and p-iodoanisole. The reaction mechanism was
Stille 偶联反应是最重要的偶联反应之一。众所周知,
三苯胂配体可以加快Stille偶联的反应速率。然而,迄今为止,尚未研究其他胂
配体的 Stille 偶联反应。在这项工作中,我们制备了 13 种C 3对称的叔胂
配体,发现三(对茴香基)胂是
三丁基乙烯基锡和对
碘茴香醚反应的最佳
配体。通过色散校正密度泛函理论计算研究了反应机理,以证明由三(对茴香基)胂介导的 Stille 偶联反应的能量可行性。
