Retracted Article: Monodisperse Pt NPs@rGO as highly efficient and reusable heterogeneous catalysts for the synthesis of 5-substituted 1H-tetrazole derivatives†
Abstract
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 and various aromatic nitriles with great catalytic performance. Pt NPs@rGO have been used for the first time for these types of synthesis reactions and these NPs were characterized by transmission electron microscopy (TEM), high resolution electron microscopy (HRTEM), X-ray diffraction (XRD), atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS). All prepared tetrazole compounds were obtained with the highest yield by using the current heterogeneous catalyst and characterized by melting point, FT-IR, 1H-NMR, 13C-NMR and HRMS analyses.
