CuFe2O4 nanoparticles: a magnetically recoverable and reusable catalyst for the synthesis of quinoline and quinazoline derivatives in aqueous media

Abstract

The synthesis of quinoline and quinazoline derivatives is attempted using magnetically separable and reusable CuFe₂O₄ nanoparticles in aqueous media. Nano sized CuFe₂O₄ was prepared by the thermal decomposition of Cu(NO₃)₂ and Fe(NO₃)₃ in water in the presence of sodium hydroxide and confirmed by X-ray diffraction patterns (XRD), scanning electron microscopy images (SEM) and transmission electron microscopy (TEM). The catalytic activity of CuFe₂O₄ nanoparticles was evaluated in aqueous media and the results show its applicability as a green, reusable and promising catalyst in organic synthesis.
