Monodisperse Pt NPs@rGO as highly efficient and reusable heterogeneous catalysts for the synthesis of 5-substituted 1H-tetrazole derivatives

摘要: Monodisperse platinum nanoparticles supported on reduced graphene oxide (Pt NPs@rGO) are stable, isolable, bottleable, long-lived, highly efficient and exceptionally reusable heterogeneous catalysts for the synthesis of 5-substituted 1H-tetrazoles from sodium azide various aromatic nitriles with great catalytic performance. Pt NPs@rGO have been used first time these types reactions NPs were characterized by transmission electron microscopy (TEM), high resolution (HRTEM), X-ray diffraction (XRD), atomic force (AFM) photoelectron spectroscopy (XPS). All prepared tetrazole compounds obtained highest yield using current catalyst melting point, FT-IR, 1H-NMR, 13C-NMR HRMS analyses.
