Magnetically separable graphene oxide supported molybdenum (Fe3O4/GO-Mo) nanoparticles were prepared and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR), and vibrating sample magnetometry (VSM) techniques. The synthesized heterogeneous material was found to exhibit high catalytic activity...
A magnetic carbon nanotube supported Cu catalyst (CoFe2O4/CNT-Cu) was prepared, characterized and evaluated as a recoverable catalyst for synthesis of 3-nitro-2-arylimidazo[1,2-a]pyridines via one-pot three-component reactions of 2-aminopyridines, aldehydes and nitromethane. The reactions proceeded in PEG 400 under aerobic conditions and the products were obtained in good to excellent yields. The...
