Carboxylic acid groups attached to an aromatic ring are reducible at cathodes of lead or mercury in sulphuric acid [127]. Oxalic acid is also reduced but in general, where the carboxyl group is attached to an aliphatic carbon as in phenylacetic acid or cyclohexanecarboxylic acid, it remains unchanged in this reaction.
