Copper-catalyzed N-Arylation of Imidazoles with Aryl or Heteroaryl Halides Facilitated by Dimethylglyoxime in Water

Copper-catalyzed N-Arylation of Imidazoles with Aryl or Heteroaryl Halides Facilitated by Dimethylglyoxime in Water

A combination of CuSO4/dimethylglyoxime was found to be an efficient and inexpensive catalyst system for N-arylation of imidazole and benzimidazole with aryl halides and heteroaryl halides in water, providing the corresponding products in moderate to good yields.
