In this work, a new synthetic route for the preparation of ZnFe 2 O 4 nanoparticles through the chemical co‐precipitation using Fe 2+ and Fe 3+ ions in an alkaline solution was developed. The synthesized nanoparticles were characterized by XRD, FTIR, SEM, ICP‐MS, DRS, TGA, VSM and elemental analysis. Characterization results confirmed the formation of single ZnFe 2 O 4 phase, with an average particle size of 40 nm and a high saturation magnetization of 34 emu g −1 . The prepared material was employed as a catalyst for the synthesis of 2‐aminotiophene derivatives through the Gewald reaction. This thermally and chemically stable nanocatalyst is environmentally benign, economical and reusable which can be easily recovered using an external magnet. Therefore, it appears that this methodology can be simply extended for industrial purposes.
