Application

N-Phenylhydroxylamine can be used as a starting material for the synthesis of:
  • 2-alkylindoles by treating with aliphatic terminal alkynes using gold catalyst via sequential 3,3-rearrangements and cyclodehydrations.
  • Isoxazolidines by reacting with aldehydes and α, β-unsaturated aldehydes via a three-component one-pot catalytic reaction.
  • Tetrahydro-1,2-oxazines by treating with an aldehyde and cyclopropane via homo 3+2 dipolar cycloaddition reaction.

Previous studies have shown that incubation of rat red blood cells in vitro with phenylhydroxylamine (50-300 microM) induces rapid splenic sequestration of the red cells on reintroduction to isologous rats. EPR and the spin trapping agent, 5,5-dimethyl-1-pyrroline-N-oxide (DMPO), were utilized

Photoinduced homolytic fission of nitrogen-oxygen bond in N,O-diacyl-4-benzoyl-N-phenylhydroxylamines using 310 nm UV light for 10 min produced acylaminyl and acyloxy radicals, which resulted in single strand cleavage of DNA at pH 7.0. Further the DNA cleaving ability of N,O-diacyl-4-benzoyl-N-phenylhydroxylamines found

Carboxyheme and metheme states modulate hemostasis in humans and other species. Further, carbon monoxide and/or nitric oxide production increase in inflammatory disorders involving the gastrointestinal tract, with associated hypercoagulability or hypocoagulability. In particular, the horse suffers both thrombotic or coagulopathic
