bipyridine‐based covalent organic polymer (COP) was successfully synthesized by condensation of trimesoyl chloride (TMC) and 2,2′‐bipyridine‐5,5′‐diamine (Bpy) under ambient conditions. This material was modified by coordination of PdCl2 to COP framework, affording a hybrid material, Pd@TMC‐Bpy COP, which was applied as a highly efficient heterogeneous catalyst for Suzuki‐Miyaura reaction under ligand‐free conditions
在环境条件下,通过偏苯三酰氯(TMC)和2,2'-联吡啶-5,5'-二胺(Bpy)的缩合成功合成了基于联吡啶的共价有机聚合物(COP)。该材料通过将PdCl 2与COP框架配位而改性,提供了一种杂合材料Pd @ TMC-Bpy COP,可作为高效的非均相催化剂用于Suzuki-Miyaura在无配体条件下在乳酸乙酯中的反应。该催化剂可以重复使用五次而不会明显丧失其活性。
