A porous organic polymer based on 4,4'-bipyridyl palladium as highly efficient heterogeneous catalysts for Suzuki cross-coupling reaction

一步法构筑了含4,4’-联吡啶钯骨架微孔聚合物材料催化剂HCP-(Bpy-Pd),通过SEM、IR和XRD等研究Pd引入方式对合成催化剂材料的形貌控制。N2吸附-脱附测试(BET)显示该催化剂具有丰富的微孔结构,比表面积达610.7 m2·g-1。HCP-(Bpy-Pd)催化剂在溴苯Suzuki偶联反应中表现出非常高的活性,80℃反应10 min,联苯产率达到99%,催化剂能够循环使用10次,通过一步法将联吡啶Pd引入催化剂骨架的方法具有重要的潜在应用价值。

Microporous organic polymer HCP-（ Bpy-Pd） based on 4,4’-bipyridyl palladium ligands was designed and synthesized,characterized by SEM,XRD and BET,and applied to Suzuki reaction while exhibiting excellent activity and selectivity. Effects of Pd adding methods on catalysts morphology were investigated. BET results showed that catalysts had abundant micro-pores and surface area was610. 7 m2·g-1. Yield of biphenyl could reach 99% when reacted for 10 min at 80 ℃. More importantly,this catalyst can be reused for 10 times without decreasing of activity. These features show that such catalyst have significant potential applications in the future.
