Abstract A simple and efficient method for the synthesis of 5-substituted tetrazoles, sulfides and sulfoxides in the presence of Pd(0) complex immobilized on mesoporous SBA-15 as an efficient, recoverable and thermally stable mesostructure has been reported. Also, the prepared mesostructure was characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, X-ray mapping, energy-dispersive X-ray spectroscopy, N2 adsorption and desorption, inductively coupled plasma optical emission spectroscopy and thermal gravimetric analysis. Then, this mesostructured catalyst was applied in the synthesis of 5-substituted tetrazoles, sulfides and sulfoxides. The approach described here offers advantages such as short reaction times, high yield, purity yields, simple and eco- friendly, easy work-up. More importantly, this nanohybrid robust catalyst did not undergo metal leaching and applied several times without any decrease in catalytic activity.
