An efficient and facile approach to synthesize imidazoles from amidines and arylketone via oxidative coupling of sp(3) C-H bond and N-H bond is reported. This strategy exhibits high performance in terms of regioselectivity with moderate to high yields by using easily available materials, and provides an alternative method to synthesize multi-substituted imidazole skeletons.
