    Abstract: A method for producing alcoxylated carbonyl compounds of general formula (I) (compounds I): R aR C(OR )b wherein R , R represent hydrogen or C1-C6-alkyl, R independently means C1-C6-alkyl, a is 0 or 1, b 2 or 3 with the proviso that the sum of a and b is 3, by means of anodic oxidation of germinal dialcoxy compounds of general formula (II) (compounds II) wherein R , R , R , R represent hydrogen or C1-C6-alkyl, R , R represent C1-C6-alkyl or C1-C6-alcoxy, in the presence of a C1-C6-alkyl alcohol (compounds III). A usual compound (compound IV) is used as a cathodic depolarizer suitable for electrochemical oxidation. The anodic oxidation and cathodic reduction is carried out in an undivided electrolyte cell in the presence of C1-C6-alkyl alcohols.

    Abstract: The invention relates to a method for producing orthocarbonic acid trialkyl esters by electrochemical oxidation of alpha-beta-diketones or alpha-beta- hydroxy ketones in the presence of C1-to C4-alcohols (alcohol A), the keto function being present in the form of a ketal function derived from C1- to C 4- alykl alcohols and the hydroxyl function being optionally in the form of an ether function derived from C1- to C4-alykl alcohols (ketal K). The molar ratio of the ketal K to the alcohols A in the electrolytes is 0.2:1 to 10:1.
