Abstract

In this research GO was modified with 3-aminopropyl triethoxysilane (APTES-GO), and then was mixed with prepared (Ni0.7Zn0.3) Fe2O4 to obtain (Ni0.7Zn0.3)Fe2O4/APTES-GO nanocomposite. The composite was characterized by FT-IR, XRD, SEM, and EDX. Results confirmed the modification of GO with APTES, and the presence of Ni, Zn, and face-centered cubic (FCC) structure of Fe2O4. Finally, composite was used as an eco-friendly catalyst in one-pot synthesis of 2-amino-4H-Chromene via three-component reaction of malononitrile, aromatic aldehydes, and resorcinol. The obtained catalyst was recovered by an external magnetic field and reused several times without significant activity loss. Resulting 2-amino-4H-chromenes were purified and then characterized by FT-IR, 13C-NMR and 1H-NMR spectrums
