Article

The Semmler-Wolff aromatization of 4-hydroxyimino-4,5,6,7-tetrahydro[2,1,3]benzoxadiazole and its 1-oxide derivative in sulfuric acid and in acetic anhydride gave 4-amino[2,1,3]benzoxadiazole and 4-acetamido[2,1,3]benzoxadiazole 1-oxide. Some reactions of the resultant amines were studied.
