The present work describes the preparation of a palladium catalyst using 5-(methylthio)-1H-tetrazole (Thio-Tet) as a ligand and 3-chloropropyltrimethoxysilane ((MeO)3Si-PrCl) as a linker, which was adsorbed onto nanomagnetic lignin (Fe3O4@LS)-Thio-Tet-Pd(II)). The resulting nanocatalyst (Fe3O4@LS-thio-Tet-Pd(II)) was successfully applied for the synthesis of arylaminotetrazoles via N-arylation of 5-amino-1H-tetrazole (5-AT) with aryl iodides. Fe3O4@LS-thio-Tet-Pd(II) was characterized using FT-IR (Fourier transform-infrared spectroscopy), XRD (X-ray diffraction), EDS (energy dispersive X-ray spectroscopy), VSM (vibrating sample magnetometer), SEM (scanning electron microscope), TEM (transmission electron microscopy), ICP-AES (Inductively coupled plasma atomic emission spectroscopy) and tetrazoles derivatives were analyzed using FT-IR and NMR techniques. The results demonstrated that the catalyst can be recycled five times without any significant decrease in catalytic efficiency, confirming its robustness.
