Abstract: Electrochemical preparation of (a) an orthocarboxylate ester (I), derived from an aliphatic carboxylic acid and, to provide alkoxy groups, a primary aliphatic alcohol (III); or (b) an orthocarbonate (Ia), derived from (III), by oxidation at a diamond electrode. To prepare (I), the electrolyte contains (III) and an aliphatic aldehyde (IV) (or its acetal in which alkoxy groups are derived from (III)), or a mixture of these compounds; and to prepare (Ia), it contains (III) and (I).
