摘要: The peroxytrifluoroacetic acid oxidation of 5-nitroso-2,4,6-triaminopyrimidine (1b) led to the formation two products: 5-nitro-2,4,6-triaminopyrimidine 1-N-oxide (2) and 1-3-di-N-oxide (3). On basis previous experience 2 was sole expected product. However, 3 represents a rather unexpected development in that di-N-oxides pyrimidine series are uncommon. yields good for both products structures assigned on elemental analysis, mass spectral data, chemical reactions. reaction sequence is also discussed.
