摘　　要：采用2-吡啶甲醛对天然高分子壳聚糖进行化学改性,再利用席夫碱结构与吡啶环氮原子的优异配位性能制备了2-吡啶甲醛席夫碱改性壳聚糖负载钯催化剂,最后将其应用于催化卤代苯和苯硼酸的Suzuki偶联。结果表明,该新型负载催化剂具有良好的催化性能和循环使用性能。The research used pyridine-2-carboxaldehyde to modify the natural polymer chitosan.By the excellent coordination properties of the Schiff-base structure and the nitrogen atom of the pyridine,the load palladium catalyst of pyridine-2-carboxaldehyd modified chitosan was prepared smoothly.Its application in the catalytic Suzuki reaction showed that this new load catalyst had good catalytic performance and cycle performance.
