Abstract

The nuances accompanying the charge transfer process for the electrochemical reduction of iron protoporphrin IX dimethyl ester chloride, Fe(ppdme)Cl, in n-butyronitrile, are revealed directly by either cyclic voltammetry at conventionally sized electrodes over the temperature range from -100 to +100 °C or by using scan rates encompassing the millivolt per second to thousands of volts per second range with microelectrodes. Both approaches lead to the conclusion that the reduction processes are best described by the square reaction scheme given below which includes chloride exchange with solvent and/or electrolyte and cross redox reactions.
