摘要
设计制备了一种多孔性的离子液体聚合材料PICP,并将Pd盐负载在材料上。作为催化剂,该纳米Pd对于芳基溴化物与苯硼酸的偶联反应表现出较高的反应活性和选择性。通过TEM、ICP-OES等分析,结果表明由于材料具有多孔、大比表面、大孔容的特性,Pd颗粒以纳米尺度均匀的分散在材料上且反应后没有损失,从而对芳基溴化物和苯硼酸的反应有着很好的催化活性。
A porous ionic copolymer material and the supported Pd nanocatalyst was developed and applied for the aryl C—C coupling of aryl bromides with phenylboronic acid efficiently.The supported Pd nanocatalyst was characterized by TEM,ICP-OES,and the results showed that Pd nanoparticles were dispersed on the surface of the highly porous material without loss.The Pd nanocatalyst was highly active for the coupling of aryl bromides with phenylboronic acid,and diaryl were obtained in excellent yields.
