Abstract

Nickel ferrite magnetic nanoparticles (NiFe$_{2}$O$_{4}$ MNPs) were prepared via the autocombustion assisted sol-gel method. The efficient catalyst was investigated by FT-IR, XRD, ICP, SEM, and TEM techniques. A one-pot, three-component reaction is reported for the synthesis of substituted 4$H$-chromenes in the presence of NiFe$_{2}$O$_{4}$ MNPs as a reusable catalyst in a green solvent at 40 $^{\circ}$C under clean, efficient, and mild conditions. Furthermore, selected products were characterized by FT-IR, $^{1}$H NMR, and $^{13}$C NMR. The single-crystal X-ray analysis of product 4u was also conclusively confirmed. Easy workup procedure, high purity of products via simple recrystallization, and environmentally benign conditions are the outstanding benefits of this method.
