Abstract: | Using the example of the reaction of 1,3,5-triazines simultaneously containing trichloromethyl and ethoxycarbonyl substituents with phenylhydrazine, it was shown that the presence of even one ester group leads to ring transformation. Depending on the number of the ester groups in the initial 1,3,5-triazine, the reaction products are either 1,2,4-triazole or 1,2,4-triazine derivatives.For Communication 8, see [1].Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 12, pp. 1655–1664, December, 1990. |
