Abstract

The electrolysis of isobutyraldehyde in the presence of water in alkaline methanol leads to α-hydroxy-isobutyraldehyde-dimethylacetal (1). The reaction probably occurs via the oxidation of the base conjugate to isobutyraldehyde to the carbenium ion and the subsequent nucleophilic addition of hydroxyl ion present in the electrolyte.
