Electrochemical Behavior of 4-keto Isophorone in Non-Aqueous Medium in the Presence of Carbon Dioxide

the kinetics of the slow coupling of co2 with the anion-radical of 4-keto isophorone (4ki) in acetonitrile and on a gold/amalgamated electrode has been analyzed by using cyclic voltammetry and double potential step chronoamperometry. the coupling rate is estimated as 0.35 s-1 and the electrode mechanism at slow sweep rates (n < 1 v s-1) is predominantly disp1.
