A novel P,N-ligand was introduced for efficient Ni-catalyzed amination of aryl chlorides. Reaction of cyanuric acid (1,3,5-triazine-2,4,6-triol) and trichlorophosphine (PCl3) resulted in the production of a new porous material (TPPM) containing triazine rings with phosphite moieties in a sheet morphology. Cavities in the prepared compound create sites on the surface of the material with appropriate
一种新型的P,N-配体被引入以有效地Ni催化芳基氯化物的胺化。氰尿酸(1,3,5-三嗪-2,4,6-三醇)与三氯膦(PCl 3)导致了一种新的多孔材料(TPPM)的生产,该材料包含片状形态的具有亚磷酸酯部分的三嗪环。制备的化合物中的空腔会在材料表面上形成具有适当连接特性的位点,以与金属配合用于催化目的。在这种容易制备且可重复使用的P,N-配体的存在下,镍催化的芳基氯化物和2,4,6-三芳氧基-1,3,5-三嗪(TAT)保护型苯酚的胺化反应得以有效完成。在温和的反应条件下。更重要的是,TPPM在遵循此协议后可重复使用5次,而其活动没有明显减少。
