Neodymium immobilized on Fe3O4: A new and recoverable catalyst for oxidation reactions and synthesis of 5‐substituted 1H-tetrazoles in green condition.

The present work, we prepared a novel catalyst by linking Nd complex on Fe 3 O 4 nanoparticles as green catalyst and characterized by FT-IR, SEM, EDX, ICP-OES, XRD and TGA methods. Then, catalytic activity of this catalyst was tested in the oxidation reactions and synthesis of tetrazoles. Easy preparation and easy separation, chemical and hydrothermal stability, the use of inexpensive materials, high reusable are outstanding properties of this protocol. Magnetic nanoparticle functionalized with neodymium complex as catalyst and characterized by SEM, XRD, FT-IR, TGA, EDX and ICP techniques. Then, catalytic activity of prepared catalyst was examined in the synthesis of tetrezoles and oxidation reactions in which observed short reaction time and high yield in these reactions.
