Various 2-aryl quanoxalines were synthesized with good yields from o-phenylene diamines and phenacyl bromides in one pot using novel nanocrystalline 5 % Fe/ZnO catalyst, at room temperature. The salient feature of this method includes mild reaction conditions, short reaction time, good yield, high purity of product, and recyclable catalyst without noticeable decrease in catalytic activity, which can be used for large-scale synthesis. The synthesized 5 % Fe/ZnO nanoparticles were characterized by using XRD, SEM, and TEM techniques.
