Synthesis of Imidazolium‐Based Ionic Liquid on Modified Magnetic Nanoparticles for Application in One‐Pot Synthesis of Trisubstituted Imidazoles

The core‐shell of Fe 3 O 4 @SiO 2 modified by epichlorohydrin and 1‐methyl‐imidazole (Fe 3 O 4 @SiO 2 ‐EPIM), a new green recyclable nanocatalyst, was designed and prepared. This nanocatalyst was characterized using fourier‐transform infrared spectroscopy (FT‐IR), field‐emission scanning electron microscopy (FESEM), energy‐dispersive X‐ray spectroscopy (EDS), elemental mapping technique, transmission electron microscopy (TEM), X‐ray diffraction...
