Ad. Malievskii et Sv. Koroteev, THE EXCHANGE-REACTION OF HYDROGEN-ATOMS IN THE SYSTEM STERICALLY HINDERED HYDROXYLAMINE-NITROXYL RADICAL, Russian chemical bulletin, 47(7), 1998, pp. 1287-1291
The rate constants of the direct and reverse exchange reactions of the
hydrogen atom in the system sterically-hindered nitroxyl radical-hydr
oxylamine of the quinoline, imidazoline, pyrrolidine, and piperidine s
eries as well as diarylhydroxylamine were determined. A scale of the r
eductive 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.
