Amination of 3,5-dibromo-4-nitrosoanilines and 3-halo-4-nitrosophenols
摘要:
Reactions of 3,5-dibromo-4-nitrosoanilines with arylamines and 3-halo-4-nitroso-phenols with alkyl- and arylamines result in the nucleophilic substitution of the halogen atoms.
1,3-Dichloro-2-nitrosobenzene and 1,3-dibromo-5-fluoro-2-nitrosobenzene reacted with amines to give previously unknown nitrosobenzene derivatives containing alkylamino groups in positions 3 and 5.

By reactions of 4-amino-2,6-dihalonitrosobenzenes with sodium azide and 4,6-dihalo-2,1,3-benzoxadiazoles with amines a group of 2,1,3-benzoxadiazole aminoderivatives was prepared.

Reactions of 4,6-dibromo-2,1,3-benzoxadiazole with phenols or arenelthiols lead to 4-aryloxy-6-bromo-2,1,3-benzoxadiazoles or 4-arylthio-6-bromo-2,1,3-benzoxadiazoles, respectively. Isomeric 6-aryloxy-4-bromo-2,1,3-benzoxadiazoles were synthesized by replacement of the fluorine atom in 2,6-dibromo-4-fluoro-1-nitrosobenzene with phenols and treatment of the resulting 4-aryloxy-2,6-dibromo-1-nitrosobenzene with sodium azide.

The addition of 1-morpholinocyclohexene to the nitroso group of polyhalonitrosoarenes gives N-(2-morpholinocyclohex-2-enyl)-N-(polyhalophenyl)hydroxylamines.
