Electrochemically generated peroxodicarbonate solution efficiently oxidizes hydroxybenzaldehydes to valuable phenols. The reaction is carried out in aqueous media without additional solvents or additives. The reaction gives high yields of up to 97% and tolerates a broad variety of substituents, as demonstrated by 20 diverse examples. It was successfully scaled to multi-gram range. This transformation
