of magnetic graphene oxide (MGO) with phenanthroline type ligand. The catalyst was characterized by several characterization methods and used as an effective magnetic heterogeneous nanocatalyst for the N-arylation of 2-amino-N-phenylbenzamide. Cu@Phen@MGO catalyst showed very good efficiency in base-free Chan–Evans–Lam coupling of arylboronic acid with 2-amino-N-phenylbenzamide at room temperature.
