replace one nitrogroup in 1,3,5-trinitrobenzene (TNB) to form the corresponding N-(3,5-dinitrophenyl)azoles in the presence of inorganic bases in aprotic dipolar solvents. The reaction pathway was found to depend on the structure of the starting azole. The benzotriazolyl and 1,2,4-triazolyl fragments activate the replacement of the meta-nitro group to virtually the same extent as the nitrogroup in TNB
