Abstract
The electrochemical behaviour of tetramethyl-pyrrolinic, -piperidinic, indolinonic and quinolinic aminoxyls and of oxygen was studied in DMF /H2O in order to evaluate the feasibility of an electron transfer proc ess between aminoxyls and superoxide anion. The rate constants of thes e reactions were calculated by applying the Marcus theory. A new mecha nism for the reaction, which operates in competition with those alread y reported in the literature involving an electron transfer process, i s proposed.
