Copper, an abundant metal on Earth, has re-emerged as a suitable alternative to versatile Palladium-catalyzed C–N coupling. Herein, a new recoverable and reusable bifunctional catalyst was synthesized by combining an ionic liquid and linking Cu(II) on the surface of Fe3O4 nanoparticles. New nanocatalyst (MNP@IAH@Cu-IL) was completely characterized using different techniques. Continuing, MNP@IAH@Cu-IL was applied in the synthesis of primary and secondary amines via C(sp2 )-N coupling reaction successfully. This catalyst worked well in the synthesis of anilines derivatives in high yields and excellent quality. Further, we described a novel and one-pot process for the synthesis of unsymmetrical secondary amine derivatives from two different aryl(alkyl) halides. This procedure shows attractive features such as 100% atom economy, high yields of the desired products under base-free conditions, excellent functional group tolerance, work-up simplicity, and recyclability
