Fe3O4 magnetic nanoparticles (Fe3O4 MNPs): A magnetically reusable catalyst for synthesis of Benzimidazole compounds

In this paper, Fe3O4 magnetic nanoparticles (Fe3O4 MNPs) were prepared and intro-duced as an efficient and eco-friendly catalyst for the synthesis of benzimidazole derivatives. The as-synthesized Fe3O4 magnetic nanoparticles were characterized by FT-IR spectroscopy and scanning electron microscopy (SEM).This method afforded the target products in high yields and the catalytic system could be recycled and reused without significant loss of catalytic activity.
