Abstract : Cu nanoparticles promoted N-arylation of NH-heterocycles, e.g., I with aryl halides ArX [Ar = 4-H3CC6H4, 2,4-(Cl)2C6H3, 4-O2NC6H4, etc.; X = Cl, I] is an effective and inexpensive method. In this synthetic protocol, good to excellent yields are obtained. Both aryl iodide and aryl bromide are compatible with the reaction conditions.
