Power intensive derivatives of 1-aryl-3-mercapto-1,2,4-triazols contain 1-(4-nitrophenyl)-1,2,4-triazolin-3-thion. In addition, they contain substances of the general formula being obtained from aryl hydrazines in 4 stages. At the first stage respective 1-arylsemicarbazides are obtained by thiocyanation. At the second stage respective 1-substituted-1,2,4-triazoline-3-tions are obtained by cyclization of obtained 1-arylsemicarbazides by an action of carboxylic acids. At the third stage respective 1-substitited-3-polynitroarylthio-1,2,4-triazols are obtained by arylation of above mentioned derivatives of 1,2,4-triazol ZHala in the presence of alkaline agents. At the fourth stage final 1-(polynitroaryl)-3-(polynitroarylthio)-5-R-1,2,4-triazols are obtained by nitration of respective substances .
