Liquid-phase ozone oxidation of condensed azoles was written by Tyupalo, N. F.;Yakobi, V. A.;Stepanyan, A. A.;Zaika, R. G.. And the article was included in Ukrainskii Khimicheskii Zhurnal (Russian Edition) in 1977.Electric Literature of C4H3N3O4 This article mentions the following:
Liquid-phase oxidation of I(X = N, CH) by O3 at 60° in H2SO4 containing MnSO4 or FeSO4 gave 83-8% II (X = CH) from benzimidazole and 65-76% II (X = N) from benzotriazole. A mechanism involving oxidation of the Fe and Mn ions by O3 was proposed. In the experiment, the researchers used many compounds, for example, 1H-1,2,3-Triazole-4,5-dicarboxylic acid (cas: 4546-95-6Electric Literature of C4H3N3O4).
1H-1,2,3-Triazole-4,5-dicarboxylic acid (cas: 4546-95-6) belongs to triazole derivatives. Triazoles are important five-member nitrogen heterocycles involved in a wide range of industrial applications such as agrochemicals, corrosion inhibitors, dyes, optical brighteners, as well as biologically active agents. Triazoles are compounds with a vast spectrum of applications, varying from materials (polymers), agricultural chemicals, pharmaceuticals, photoactive chemicals and dyes.Electric Literature of C4H3N3O4
