Abstract: The self-reactions of a series of acyl methyl nitroxides have been studied in solution, These reactions proceed by p-disproportionation, for which the measured rate contants lie in the range 10'-103 M-'sl at 298 K. Arrhenius parameters derived from the kinetic data are unusual, having low A factors (ca. IO4 M-'s-]) and low activation energies (ca. 1-4 kcal/mol); such values indicate that the reactions do not proceed by a simple ...
