Synthesis and photochemical decomposition of some substituted 1,2-, 1,2,3- and 1,2,4-azafulfenes was written by Burgess, Edward M.;Sanchez, Joseph P.. And the article was included in Journal of Organic Chemistry in 1974.Synthetic Route of C5H7N3O2 This article mentions the following:
A series of phenylpyrazole and -triazole diphenylcarbinols have been converted to the hydrochloride salts of the carbinyl chlorides and thence to the corresponding azafulvenes by dehydrohalogenation with triethylamine at -78°. Irradiation of the triazafulvenes at this temperature gave a mixture of isolable products which implicate azatriafulvene and azete as possible unstable precursors. The latter intermediate may also be involved in the photochem. decomposition of triphenyltriazine which was also examined The diazafulvenes prepared proved isolable but photochem. inert. In the experiment, the researchers used many compounds, for example, Ethyl 1H-1,2,3-triazole-5-carboxylate (cas: 40594-98-7Synthetic Route of C5H7N3O2).
Ethyl 1H-1,2,3-triazole-5-carboxylate (cas: 40594-98-7) belongs to triazole derivatives. Triazoles consist of a five-membered ring containing three nitrogen atoms and are biologically active, especially as antifungal, antimicrobial and enzyme inhibitors. Many triazoles have antifungal effects: the triazole antifungal drugs include fluconazole, isavuconazole, itraconazole, voriconazole, pramiconazole, ravuconazole, and posaconazole and triazole plant-protection fungicides include epoxiconazole, triadimenol, myclobutanil, propiconazole, prothioconazole, metconazole, cyproconazole, tebuconazole, flusilazole and paclobutrazol.Synthetic Route of C5H7N3O2
