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
