Hyperbranched polymer immobilized palladium nanoparticles as an efficient and reusable catalyst for cyanation of aryl halides and reduction of nitroarenes

A new nitrogen-rich hyperbranched polymer comprising imidazolium and triazole moieties used for stabilization of Pd nanoparticles. The resulting material, [email protected] NPs, was characterized with different techniques including Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), photoelectron (XPS), energy dispersive X-Ray (EDX), transmission electron microscopy (TEM) analysis. NPs has been as an efficient catalyst in the reduction nitroarenes to amines cyanation aryl bromides iodides. showed high stability recyclability recycled at least 10 times 1?chloro-4-nitrobenzene 5 iodobenzene.
