Abstract
The decay kinetics of the free radical produced electrochemically by monoelectronic oxidation of Phenidone has been studied by polarography, spectrophotometry and ESR spectrometry at different pH's, temperatures and reagent concentrations. The results obtained with the three techniques, together with the information of flash photolytic experiments, prove that the red-orange decaying species responsible for the cathodic polarographic wave is a primary free radical product of oxidation. The kinetic data indicate that a dismutation of the radical is the rate determining step. The preliminary results on some derivatives of Phenidone are also reported.
