Magnetically recyclable CuFe2O4 nanoparticles as an efficient and reusable catalyst for the green synthesis of HBIW

Magnetic nanoparticles of copper ferrite (CuFe2O4 MNPs) have been simply prepared and applied as an efficient, recyclable and reusable catalyst for the green synthesis of 2,4,6,8,10,12-hexabenzyl-2,4,6,8,10,12-hexaazatetracyclo[5.5.0.05,9.03,11]dodecane (HBIW). The structure of the synthesized pure HBIW (recrystallization from ethanol) was confirmed by using various spectral techniques like IR, 1H-NMR, 13C-NMR and some of its physical properties. The prepared catalyst was characterized by SEM, XRD and FT-IR. In addition, CuFe2O4 MNPs could be reused up to seven runs without any significant loss of activity. Finally, the remarkable advantages of this method are the simple experimental procedure, shorter reaction times, simple work-up and green aspects by avoiding toxic catalysts and high yield of product.
