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.

Pseudomonas pseudoalcaligenes JS45 grows on nitrobenzene as a sole source of carbon, nitrogen, and energy. The catabolic pathway involves reduction to hydroxylaminobenzene followed by rearrangement to o-amino-phenol and ring fission (S. F. Nishino and J. C. Spain, Appl. Environ. Microbiol....

Cigarette smoking is associated with plasmatic hypercoagulability, and carbon monoxide has been demonstrated to enhance coagulation by binding to a fibrinogen-bound heme. Our objective was to design and test a redox-based method to detect carboxyhemefibrinogen. Normal, pooled, citrated plasma was...

Hydroxylamino aromatic compounds are converted to either the corresponding aminophenols or protocatechuate during the bacterial degradation of nitroaromatic compounds. The origin of the hydroxyl group of the products could be the substrate itself (intramolecular transfer mechanism) or the solvent water...
