| Abstract: | The N-oxides of 2- and 2,3-substituted pyrazines were synthesized. It was found that the synthesized 2-formylpyrazine N,N -dioxide, in which the aldehyde group is in the hydrated form, undergoes redox transformations leading to deoxidation of one of the ring nitrogens and oxidation of the dihydroxymethyl group to a carboxyl group under the influence of alkaline reagents.See 10] for communication II.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 9, pp. 1275–1280, September, 1972. |
