Abstract

A method for the synthesis of 2-(1,3-diphenyl-1H-1,2,4-triazol-5-yl)-2,2-dinitroacetonitrile was developed, and its reaction with diazomethane was investigated to show the reaction involves 1,3-dipolar cycloaddition and forms a separable mixture of 4-[(1,3-diphenyl-1H-1,2,4-triazol-5-yl)dinitromethyl]-2H-1,2,3-triazoles. The latter react with KOH in ethanol to form potassium salts of 4-[(1,3-diphenyl-1H-1,2,4-triazole-5-yl)aci-nitromethyl]-1,2,3-triazoles.
