Synthesis and characterization of nano-copper ferrite as a magnetically separable catalyst for the one-pot synthesis of 2,4,5-trisubstituted and 1,2,4,5-tetrasubstituted imidazoles under solvent-free condition

The authors report herein, synthesis and characterization of nano-copper ferrite as a recoverable, eco-friendly, inexpensive, and readily available catalyst for efficient, simple, and green synthesis of multi-substituted imidazoles. Short reaction times, high yields, easy workup, and mild condition are the advantages of this protocol. The catalyst can be reused without evident loss of the catalytic activity. Characterization of the catalyst was performed fully by Fourier transform infrared spectra, X-ray diffraction, FESEM, electron dispersive X-ray, and vibration sampling magnetometer analyses.
