Condensation of tetrazolylhydrazone of ethyl nitroglyoxalate with aromatic amines gives rise to derivatives of 5-arylamino-6-oxo-6,7-dihydrotetrazolo[5,1-b][1,2,4]triazine.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 12, pp. 1668–1672, December 1986.  相似文献

The reaction of the tetrazolediazonium ion with malonic acid dinitrile and nitroacetonitrile leads to the formation of 3-azido-5-amino-1,2,4-triazine derivatives. According to the mass-spectrometric data and the results of X-ray diffraction analysis, the crystalline compounds exist in the amino form. The facile hydrolysis of the amino and azido groups to azauracils is an argument in favor of the existence of the imino form in solution.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 4, pp. 557–561, April, 1984.  相似文献
