Abstract Reductive denitration of 1-trinitromethyl-3-R-1, 2, 4-triazoles by KI or NH 2 OH followed by the treatment of the formed 1-dinitromethyl-3-R-1, 2, 4-triazoles salts with sulfuric acid yielded dinitromethyl compounds (R= H, N 3, Cl, NO 2), sufficiently strong CH-acids (pK a 1.37–0.12) whose typical reactions are similar to those of gem-dinitrocompounds from the aliphatic series. The spectral data and the analysis of correlation relations between pK a ...
