Kinetic studies on the single electron transfer reaction between 2,2,6,6-tetramethylpiperidine oxoammonium ions and phenothiazines: the application of Marcus theory*
Vol.42 No.2 SCIENCE IN CHINA (Series B)，-0001，（）：
Electron transfer reactions take place readily between 2,2,6,6-tetramethylpiperidine oxoammonium ions (1a, 1b) and phenothiazines (2a--2g), giving corresponding nitroxides (3a, 3b) and phenothiazme radical eations (4a--4g). The rate constants for the electron self-exchange reactions between 1 and 3, as well as between 2 and 4, are determined by EPR and IH NMR line-broadening effect in acetonitrile. Fay application of the Marcus theory, the kinetics of the cross-exchange reactions between 1 and 2 is studied.
