  • The presence of nitro groups in the pyrolized products is then detected.
  • Additionally, SnCl 2 is used to selectively reduce aromatic nitro groups to anilines.
  • It is an para to a nitro group.
  • Azides are cleanly reduced to amines in preference to sterically hindered aliphatic nitro groups:
  • Derivatives have been prepared by nucleophilic displacement of the nitro groups with azide and hydrazine.
  • The explosive tendencies of aromatic nitro compounds are increased by the presence of multiple nitro groups.
  • A nitro group is a molecular fragment consisting of a nitrogen atom bonded to two oxygen atoms.
  • This technology is based on decomposition of explosive substance followed by the reduction of the nitro groups.
  • Reductive alkylation of the nitro group affords secondary aryl amines, which are useful antioxidants for rubber.
  • Later, the chemists found a way to substitute six nitro groups for hydrogen atoms, yielding hexanitrocubane.
  • The second substitution reaction ( on the right ) is slower because the first nitro group is deactivating.
  • They postulated the correlation of different bands to specific groupings, for instance the nitro group in nitrobenzene.
  • The NiCl 2 / NaBH 4 system reduces aliphatic nitro groups, nitriles and oximes completely to amines.
  • A more water-soluble nitro group found in dantrolene, and is 30 times more water-soluble.
  • "' Heptanitrocubane "'is a new experimental nitro groups, giving the final molecular formula.
  • This technology has significantly more false alarms because many other harmless compounds also have an abundance of nitro groups.
  • It has an anisole ( methoxybenzene ) core, with two nitro groups (  NO 2 ) attached.
  • With iron and acetic acid DNAN nitro groups can be reduced to amines forming 2, 4-diaminoanisole.
  • In recent years, developing increasingly complex synthesis techniques, the team added yet another nitro group, yielding heptanitrocubane.
  • Syn addition is favored with 99 % nitro group hydrogen bonded to the protonated amine in the proline side group.
