摘要

The reaction of halonitrobenzenes with t-butyl N-hydroxycarbamate (2), gave t-butyl N (nitroaryloxy) carbamates (3), which yielded on acidolysis with trifluoroacetic acid, O- (nitroaryl) hydroxylamines (4). Compounds 4 were utilized for the amination of anionic nitrogens and of carbanions. Attempts to apply the method to the synthesis of hydroxylamines substituted on the oxygen by heterocyclic rings (pyridine, pyrimidine, ...
