Аннотация

Tetrazolium-5-dinitromethylide sodium salt has been prepared (91%) by cyclization of 1-amino-1-hydrazino-2,2-dinitroethene with  nitrous acid in water. 5-Imino-1-(hydroxy-
iminonitromethyl)-derivatives were obtained by  nitration of 2-(5-amino-1,3-dimethyl-1H-1,2,4-triazol-4-ium-4-yl)- and 2-(5-amino-4-methyl-1H-tetrazolium-1-yl)acetate complex salts. Treatment of 4-methyl-1-(2-oxopropyl)-1-tetrazolium  methylsulfate with nitric and sulfuric acid gave methyl  (3-nitro-1,2,4-oxadiazol-5-yl)amine (27%) probably via dinitromethylide followed by cyclization and loss of nitrogen.
