polymeric organic support (TPA) was synthesized successfully by a controllable one‐pot method using melamine (1,3,5‐triazine‐2,4,6‐triamine) and trichlorophosphane (PCl3). The TPA substrate is a material incorporating P and N atoms which can coordinate with metals as a pincer ligand to stabilize them, providing an efficient heterogeneous support to prepare recyclable transition metal catalyst systems.

可控的一锅法成功地使用三聚氰胺(1,3,5-三嗪-2,4,6-三胺)和三氯膦(PCl 3)合成了新型三嗪-膦胺聚合物有机载体(TPA))。TPA基材是一种结合有P和N原子的材料,它们可以与金属作为钳位配体进行配位以稳定它们,从而为制备可回收的过渡金属催化剂体系提供了有效的异质载体。在这项研究中,TPA被用作在表面上约8 nm范围内固定铱纳米粒子的载体,从而产生了新型铱纳米催化剂系统(INP-TPA-POP)。该催化剂体系使用不同的显微和光谱技术进行了表征,例如FT-IR,TEM,XPS,XRD,SEM,EDX,元素分析,ICP和BET分析。INP‐TPA‐POP纳米催化剂使用甲酸作为乙醇中的还原剂,在将醛类还原为醇类方面表现出显着的活性。
