摘要:
A method for producing alcoxylated carbonyl compounds of general formula (I) (compounds I): R1aR2C(OR3)b wherein R1, R2 represent hydrogen or C¿1?- C6-alkyl, R?3¿ independently means C¿1?- 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?4, R5, R6, R7¿ represent hydrogen or C¿1?- C6-alkyl, R?5, R6¿ represent C¿1?- 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.
