Samsonov,Sal’nikov,Genayev

, p. 2369 - 2375 (2009)

Synthesis of 6-hydroxy-6H-[1,2,3]triazolo[4,5-e][2,1,3]benzoxadiazole and a mixture of isomeric 6-hydroxy-6H-[1,2,3]triazolo[4,5-e][2,1,3]benzoxadiazole- 1(3)-oxides is carried out starting from 2,4-dinitrosoresorcinol. Total assignment of the signals in the 13C NMR spectra of O-methylated products of these compounds is performed.
