Method for producing alcoxylated carbonyl compounds by an anodic oxidation method using a cathodic coupled reaction for organic synthesis

摘要

A method for producing alcoxylated carbonyl compounds of general formula (I) (compounds I): R¹_aR²C(OR³)_b wherein R¹, R² represent hydrogen or C₁-C₆-alkyl, R³ 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 R⁴, R⁵, R⁶, R⁷ represent hydrogen or C₁-C₆-alkyl, R⁵, R⁶ 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.
