Thin film formation of Pd/reduced-graphene oxide and Pd nanoparticles at oil-water interface, suitable as effective catalyst for Suzuki-Miyaura reaction in water

A facile and efficient route was used to synthesise Pd nanoparticles by reduction of an organopalladium(II) complex, [PdCl2(cod)] (cod = cis,cis-1,5-cyclooctadiene), at the oil-water interface. Pd/reduced-graphene oxide and Pd free stabilizer nanoparticle thin films were characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction and transmission electron microscopy (TEM). Our study shows that both of these nanoparticles were suitable for the Suzuki-Miyaura carbon-carbon coupling reaction. Compared to the classical reactions, this method consistently has the advantages of a green solvent, short reaction times, low catalyst loading, high yields and reusability of the catalyst. Furthermore, Pd nanoparticles show a high catalytic activity toward aryl chloride derivatives.
