Full TextAbstract
Tannic acid immobilized on functionalized magnetic hydrotalcite (Fe3O4/HT-GLYMO-TA) was synthesized as a durable, environmentally-friendly and magnetic nanostructured catalyst for the synthesis of 5- and 1-substituted-1H-tetrazoles. The nanocatalyst was characterized by several methods, Fourier transform infrared (FT-IR), X-ray diffraction (XRD) analysis, transmission electron microscopy (TEM), field emission scanning electron microscopy (FE-SEM), energy-dispersive X-ray spectroscopy (EDS), EDS-map, thermogravimetric analysis (TGA), vibrating sample magnetometry (VSM) and CHNS analysis. The results displayed that the superparamagnetic catalyst with a mean particle size of approximately 23–27 nm has a plate-like shape. The catalytic activity of this new nanostructured catalyst resulted in the preparation of tetrazoles with high yields. Additionally, this novel procedure offers a plethora of benefits including short reaction times, the simplicity of operation, the ease of purification procedure and the reusability of nanocatalyst for at least eight cycles.
