ARYLAZO- AND ARYLAZOXY-N-NITROFORMAMIDINES
Luk'yanov, O. A.,Mel'nikova, T. G.,Strelenko, Yu. A.
, p. 997 - 1002 (1991)
Phenylhydrazine reacts with S-methylisothionitrourea to give 2-phenylhydrazino-N2-nitroformamidine, which on oxidation and nitration affords novel arylazo- and arylazoxy-N2-nitroformamidines.The structures of the products were confirmed by 1H, 13C, and 14N NMR.
