Zinc(II)–adenine complexes were functionalized on Fe3O4 nanoparticles via a versatile, simple, and inexpensive procedure. This nanostructural material was characterized by FT-IR spectroscopy, XRD, ICP-OES, TGA, EDS, and SEM techniques. The catalytic activity of this novel catalyst has been studied in some organic reactions such as oxidation of sulfides, oxidative coupling of thiols, and synthesis of 5-substituted tetrazoles. One of the outstanding advantages of this nanocatalyst is its easy separation from reaction media by an external magnet.
