Synthesis and Reactivity of Rhodium(II) N-Triflyl Azavinyl Carbenes was written by Grimster, Neil;Zhang, Li;Fokin, Valery V.. And the article was included in Journal of the American Chemical Society in 2010.Electric Literature of C5H7N3O2 This article mentions the following:
Highly reactive rhodium(II) N-trifluoromethylsulfonyl azavinyl carbenes are formed in situ from NH-1,2,3-triazoles, triflic anhydride, and rhodium carboxylates. They rapidly and selectively react with olefins, providing cyclopropane carboxaldehydes and 2,3-dihydropyrroles in generally excellent yields and high enantio- and diastereoselectivity. In the experiment, the researchers used many compounds, for example, Ethyl 1H-1,2,3-triazole-5-carboxylate (cas: 40594-98-7Electric Literature of C5H7N3O2).
Ethyl 1H-1,2,3-triazole-5-carboxylate (cas: 40594-98-7) belongs to triazole derivatives. Among the nitrogen-containing heterocyclic compounds, triazoles emerge with superior pharmacological applications. 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.Electric Literature of C5H7N3O2
