Abstract:
A novel Fe3O4@SiO2@(CH2)3N+Me3I3- magnetite nanoparticle was prepared and utilized in the synthetic conversion of aldehydes to imidazole derivatives in solvent-free conditions. These functionalized magnetic core–shell nanoparticles (MNPs) were characterized by Standard technique such as TEM, SEM, EDX, FT-IR, XRD, and VSM. The work up of reaction was very simple containing only a magnetic decantation. This novel catalyst could be separated easily and recycled several times without any significant decreasing of catalytic activity.
