摘要：

Functionalized magnetic core-shell nanoparticles [Fe3O4/SiO2/(CH2)(3)N+Me3Br3- are prepared by co-precipitation method, characterized by transmission electron microscopy, FT-IR, X-ray diffraction, and vibrating sample magnetometer. The catalytic activity of these nanoparticles was tested in the syntheses of imidazole, benzothiazole, and perimidine derivatives, under solvent-free conditions. The catalyst was readily recycled by the use of an external magnetic field and could be reused five times without significant loss of activity or mass. (C) 2014 Elsevier B.V. All rights reserved.
