Abstract Superparamagnetic CuFe 2 O 4 nanoparticles were synthesized from CuCl 2 and FeCl 3 by a co-precipitation method in ethylene glycol and characterized by several techniques, which included vibrating sample magnetometry, XRD, SEM, TEM, atomic absorption spectrometry, and nitrogen physisorption measurements. The CuFe 2 O 4 nanoparticles could be used as a solid catalyst for the α-arylation reaction of ...
