example, N2,N2′‐di‐1‐(4‐methoxyphenyl)‐ethanyloxylic‐(bishydrazide), are novel and effective ligands for copper‐catalyzed Ullmann‐type CN coupling reaction in water. A variety of amines could be effectively N‐arylated with aryl halides under both microwave irradiation and conventional heating (even at 30 °C) with good to excellent yields.
