Conclusions
On the example of the electroreduction of benzaldehyde it was shown that it is theoretically possible to obtain the alcohol in quantitative yield by suppressing the formation of pinacols; for this it is necessary to use low concentrations of benzaldehyde and high concentrations of a potassium salt in the buffer solution with a pH of 6.0–6.5 at potentials of −2.0 V (relative to the satd. calomel electrode).
