  Synthesis and Characterization of (Perfluoroaryl)borane-Functionalized Carbosilane Dendrimers and Their Use as Lewis Acid Catalysts for the Hydrosilation of Acetophenone

  摘要：

  Carbosilane dendrimers capped with 4, 8, and 12 perfluoroarylborane Lewis acids are prepared via a self-catalyzed silation of the aryl ether 1 with the appropriate Si-H terminated dendrimer scaffold. The dendrimers were fully characterized by spectroscopic methods and MALDI-TOF mass spectrometry and tested as catalysts for the hydrosilation of acetophenone using triethylsilane, exhibiting only slightly inferior activities in comparison to B(C6F5)(3).

  光诱导聚合物受阻自由基对作为材料和光催化剂的构建模块

  摘要：

  聚合物受阻路易斯对，或聚（FLP），有助于弥合功能聚合物科学和主基团催化之间的差距，将空间受阻路易斯酸和碱的独特性与聚合物支架配对，以创建自修复凝胶和可回收催化剂。然而，它们在自由基化学中的应用是前所未有的。在本文中，我们公开了通过 FLP 部分的原位光诱导合成聚合物受阻自由基对或聚（FRP），其中它们的路易斯酸性和碱性中心被调节以促进单电子转移（SET）。通过对化学结构的系统操作，我们证明了膦单体上包含邻甲基对于实现 SET 至关重要。通过紫外/可见光和 EPR 光谱监测稳定的聚合膦自由基阳离子，可以证明自由基的产生。这些新型聚（FRP）能够实现催化氢化和自由基介导的光催化全氟烷基化。这些聚合物自由基系统为设计用于催化和光电化学的新型功能聚合物开辟了新途径。
