Cu nanoparticles promoted N-arylation of NH-heterocycles with aryl halides 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.

The easy-to-prepare dimeric bis(μ-iodo)bis((-)-sparteine)dicopper(I) complex is shown to be a versatile catalyst for N-arylation of number of NH-heterocycles with structurally divergent aryl halides including activated aryl chloride substrates under mild conditions. The DFT studies not only provide structural insights into square-pyramidal Cu(III) intermediate complexes derived from (-)-sparteine, but also highlight the important role of sterically demanding (-)-sparteine ligand framework in promoting activation of aryl-chlorine bonds for N-arylation of imidazoles.
