摘要

以修饰的Hummers法制备的氧化石墨烯为载体，席夫碱为配体制备了一种新型的负载型钯催化剂，采用红外光谱仪、透射电镜、X射线光电子能谱仪、热重分析仪和X射线衍射仪等手段对负载型催化剂进行了表征，并评价了其对水相Suzuki反应的催化活性. 结果表明，该催化剂在较温和的实验条件下即可高效催化水相芳基卤与芳基硼酸的Suzuki反应，催化剂重复使用5次后，活性基本不变.

Abstract

Graphene oxide prepared by modified Hummers method was used to immobilize Shiff base palladium complex. The novel supported catalyst was characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray potoelectron sectroscopy (XPS), termogravity (TGA) and furier transform infrared spectrometer (FTIR). The supported palladium compound is an efficient catalyst for Suzuki reaction of aryl halides with phenylboronic acid to substituted trans-cinnamic acid or trans-stilbene at atmospheric condition in aqueous media, and the catalyst could be steadily dispersed in the reaction mixture. The supported catalyst still remains high activity after repeatedly five times.

Key words： graphene oxide; Schiff base; Suzuki reaction; palladium catalyst
