Influence of Some Metal Salts on the Electroreduction of Aryl Ketones1

The electrolytic reduction of 2, 3:6, 7-dibenzotropone was studied in aprotic solvent in the presence of various anhydrous metal salts. While the cyclic voltammogram shows this reaction to be a reversible one-electron reduction in CH3CN and DMF, the presence of salts such as C0Cl2 and Ni(acac)2 is found to affect the reversibility of the electrochemical reaction without influencing the reduction potential. © 1978, American Chemical Society.
