CuFe2O4 nanoparticles: an efficient heterogeneous magnetically separable catalyst for synthesis of some novel propynyl-1H-imidazoles derivatives
The non-toxic magnetic CuFe2O4 nanoparticles have been synthesized, characterized, and used as an efficient catalyst for synthesis of new derivatives for 1,2,4,5-tetrasubstituted imidazoles in excellent yields. The synthesized compounds work-up easy and purification of products are performed without chromatographic methods. The catalyst can be recovered for the subsequent reactions and reused without any appreciable loss. Read more

Magnetic NiFe2O4 nanoparticles: efficient, heterogeneous and reusable catalyst for synthesis of acetylferrocene chalcones and their anti‐tumour activity
A robust synthesis of magnetic NiFe2O4 nanoparticles via a hydrothermal technique was investigated. The prepared magnetic NiFe2O4 nanoparticles were characterized using powder X‐ray diffraction (XRD), scanning electron microscopy, transmission electron microscopy (TEM), high‐resolution TEM, energy‐dispersive X‐ray spectroscopy, thermogravimetric analysis, infrared spectroscopy and vibrating sample magnetometry. XRD and TEM analyses confirmed the formation of single‐phase ultrafine nickel ferrite nanoparticles with highly ... Read more
