Abstract

Abstract: Monodisperse Pd/Co nanoparticles (Mw−Pd/Co@CNT NPs) decorated multi‐walled carbon nanotubes have been reproducibly and easily synthesized by microwave assisted method. They were found to be remarkable catalysts for the preparation of tetrazole derivatives which have significant benefits in wide range of drug purposes. Mw−Pd/Co@CNT NPs were characterized by X‐ray diffraction (XRD), transmission electron microscopy (TEM), high resolution transmission electron microscopy (HR‐TEM) and X‐ray photoelectron spectroscopy (XPS). The results showed the fact that the prepared catalysts are highly crystalline, monodisperse and colloidally stable. The catalytic performance of these NPs was examined for any preparation of tetrazole derivatives and it's found that these Mw−Pd/Co@CNT NPs showed extraordinary catalytic activity, stability and durability. All products were provided with perfect yield in addition to shortest reaction time by employing Mw−Pd/Co@CNT as a heterogeneous catalyst. Our synthesis process comes with a facile and eco‐friendly option to Mw−Pd/Co@CNT, allowing further scrutiny of current catalysts for numerous other chemical reactions. Abstract : Monodisperse PdCo@MWNT catalyst showed excellent yield, shortest reaction time for the synthesis of 5‐Substituted 1 H ‐tetrazoles
