| 摘 要： | 以天然木质素为原料, 用甲醛对其进行交联得到了交联木质素, 通过简单的方法合成了负载钯催化剂, 用XPS、 TG、 DTA等对其进行了表征. 该催化剂在空气氛围中能很好的催化乙烯基化合物与芳基碘的Heck反应. 如在较低的温度下(40 ℃)催化丙烯酸与碘苯的反应, 产率高达73.7%, 显示了较高的催化活性. 该催化剂重复使用5次, 产率仍高达90%, 显示该催化剂有良好的重复使用性能.

| Abstract: | Cross-linking lignin complex was readily synthesized from natural lignin and the formaldehyde was used as a Cross-linking agent.The prepared complex was used as a matrix to support palladium chloride.Cross-linking lignin supported palladium complex was characterized by XPS,TG,DTA and was applied as a heterogeneous catalyst for heck reaction of compounds containing the vinyl with aryl iodide.It was found that the heck reaction could be efficiently catalyzed by the catalyst at atmospheric condition.Especially... |
