Due to the multifaceted reactivities of cyclopropenes, the divergent hydrofunctionalization of these compounds has recently attracted significant attention. Herein, we present a Pd-catalyzed hydrocyanation of cyclopropenes via aluminum Lewis acid-controlled divergent chemoselectivity. In this study, the presence of aluminum Lewis acid plays a pivotal role in the reaction pathway. In the absence of aluminum Lewis acid, the reaction predominantly yields ring-opening hydrocyanation products, whereas the addition of Lewis acid directs the formation of ring-retentive products.

Lewis 酸控制 Pd 催化的环丙烯化学分歧氢氰化反应


由于环丙烯的多方面反应性，这些化合物的不同氢功能化最近引起了极大的关注。在此，我们提出了一种 Pd 催化的环丙烯氢氰化反应，通过铝路易斯酸控制的发散化学选择性。在这项研究中，铝路易斯酸的存在在反应途径中起着关键作用。在没有路易斯酸铝的情况下，反应主要产生开环氢氰化产物，而添加路易斯酸会指导留环产物的形成。
