A palladium-catalyzed C–H arylation reaction of nitroimidazoles and nitropyrazoles was developed using aryl bromides as arene donors. The electron-withdrawing effect of the nitro group allows for direct C–H arylation reactions of the nitro diazoles with high regioselectivity under mild conditions. The new C–H arylation approach is thus complementary to nucleophilic substitution reactions, enabling the preparation of complex nitroazole compounds.
