Graphene Oxide‐Supported Palladium Complex: Synthesis, Characterization and Application in Cross-Coupling Reactions

Graphene oxide (GO) possesses a number of advantageous properties, such as twodimensional planar structure, large surface area, chemical and mechanical stability,superb conductivity and good biocompatibility [1]. Graphene oxide as a substrate for a variety of chemical transformations has been reported. The transition-metal-catalyzed carbon-carbon and carbon-heteroatom bond-forming reactions are important fundamental transformations in synthetic chemistry [2]. Inspiring from recent developments in the field of nanocatalyst [3], herein, we report preparation and characterization of GO- supported palladium complex with terpyridinbased ligands which has also been applied as an effective nanocatalyst for the C−C, C−N, C-S and C-O bond formations via cross-coupling reactions of aryl halides. In addition, the catalyst can be reused up to four times without losing much of its activity
