Efficient synthesis of aryl amines from aryl halides in the presence of melamine-supported CuO nanocatalyst in water

In this research, an efficient procedure is reported for the synthesis of aryl amines from aryl halides using aqueous ammonia in the presence of melamine-supported CuO nanocatalyst (M-CuO-nanocatalyst) in water. The catalyst was prepared by co-precipitation method and characterized by various techniques such as SEM, EDS, TGA, XRD , XRF, and BET analysis.Various aryl halides reacted with aqueous ammonia and corresponding aryl amines were obtained in relatively short reaction times and high yields. M-CuO-nanocatalyst is a stable, safe and high performance catalyst that working with it is easy. It can be easily separated from the reaction medium. M-CuO nanocatalyst is easily prepared, easy to handle and recyclable and up to 6 consecutive runs catalyzes the synthesis of aryl amines well. It could be reused more than 6 times without considerable loss of its initial activity. Furthermore, heterogeneous reaction conditions, clean procedure, simple work-up, high yields of products and short reaction times are other advantages of this method.
