摘要：

Reductive denitration of 1-trinitromethyl-3-R-1,2,4-triazoles by KI or NH2OH 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, NO2), 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) of 1-dinitromethyl-3-R-1,2,4-triazoles and the substituent constants confirm that their structure is analogous to that of the majority of compounds belonging to the mentioned series.
