Abstract Alkaline hydrolysis of mono-and dinitro derivatives of five-membered heterocycles, viz., pyrazole, imidazole, 1, 2, 4-triazole, and isoxazole, is accompanied by the elimination of the nitro group in the form of a nitrite anion. The hydrolysis kinetics was studied by the polarographic and photometric methods. The experimentally determined hydrolysis rate constants depend on the nature of the heterocycle. A possible mechanism for hydrolytic ...
