The N-arylation of a series of nitroazoles has been studied with the aid of diaryliodonium salts in the presence of CuI under the action of microwave radiation. It was found that alkylation proceeds regioselectively in each actual case with the formation of one of two possible isomers. The correct structure of the N-arylation products was established on the basis of NMR spectroscopy.
