What is On the electrochemical reduction mechanism of indolinone nitroxide radicals in DMF about?

A study of the electroreduction of 1,2-dihydro-2-phenyl-2-alkyl (or phenyl)-3 H-indol-3one-l-oxyls (nitroxide radicals) in dimethylformamide is presented. The techniques of ac and dc voltammetry, controlled potential coulometry, ESR and UV spectrometry were used. In DMF--H20 nitroxide radicals are reduced in two steps: the first is the reversible monoelectronic formation of the corresponding N-hydroxides, while the second (which involves a chemical reaction) is the irreversible production of 2,3-dihydro-2-phenyl-2-alkyl (or phenyl)-3-hydroxy indoles. A multistep scheme is suggested, based upon the electrochemical and spectrometric data.
