摘要：
The rate constants of the direct and reverse exchange reactions of the hydrogen atom in the system sterically-hindered nitroxyl radical-hydroxylamine of the quinoline, imidazoline, pyrrolidine, and piperidine series as well as diarylhydroxylamine were determined. A scale of the reductive abilities of the hydroxylamines was established. A low value of the isotope effect is typical of the reactions of hydrogen exchange in the systems hydroxylamine-nitroxyl radical.
