Benzaldehyde undergoes an EC reduction mechanism with an anion dimerization as the following reaction. Digital simulation techniques give values of the second order rate coefficients of k//2 equals 2. 4 multiplied by 10**3 liters/mole-sec. Para-cyanobenzaldehyde undergoes a mixed reduction mechanism. At low disk currents in the reduction intermediate is proposed to be a parent-anion complex. At higher fluxes, dimerization becomes the significant following process; k//2 equals 45 liters/mole-sec. A single electroactive intermediate is observed for the first one-electron reduction of p-nitrobenzaldehyde. The single, chemically, reversible redox mechanism for this compound in sulfolane agrees with spectroelectrochemical results.
