Synthesis of xanthene derivatives by employing Fe3O4nanoparticles as an effective and magnetically recoverable catalyst in water

An efficient and environmentally adapted synthesis of xanthene derivatives by condensation of a wide range of aryl aldehydes and 1,3-cyclohexanediones in water using a catalytic amount of Fe3O4 nanoparticles is explained. The Fe3O4 nanoparticles were characterized by powder X-ray diffraction (XRD), transmission electron microscopy (TEM) and FT-IR spectroscopy.
