Abstract: | It is demonstrated that ethylene oxide forms N--hydroxyethyl derivatives of the corresponding triazolin-3-ones in the reaction with 1-phenyl- and 4-phenyl-1,2,4-triazolin-3-thiones and with 3--hydroxyethylthio derivatives of 1-phenyl- and 4-phenyl-1,2,4-triazole in acetic acid. 1-Phenyltetrazolin-5-thione reacts similarly with ethylene oxide. Under the influence of ethylene oxide, 2-methyl-4-phenyl-1,2,4-triazolin-3-thione is converted to 2-methyl-4-phenyl-1,2,4-triazolin-3-one.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 5, pp. 700–703, May, 1971. |
