Synthesis of trinitromethyl and dinitromethyl-substituted azoles employing a mild and efficient nitration method has been developed using a mixture of sulfuric acid and an inorganic nitrate salt XNO3, where X = NH4 +, Na+, K+. This methodology exhibits clear advantages over the more popular mixed acids nitration approach. Various nitro functionalities such as C-trinitromethyl, N-trinitromethyl, and
