摘要： The invention relates to a process for the preparation of alpha-substituted carboxylic acids from the series comprising alpha-hydroxycarboxylic acids and N-substituted-alpha-aminocarboxylic acids by cathodic carboxylation with carbon dioxide of a compound corresponding to the general formula R¹-C(=X)R² which is constituted by aldehydes, ketones or N-substituted imines. This carboxylation has hitherto taken place in an undivided electrolytic cell with the use of a sacrificial anode. According to the invention the carboxylation takes place in the absence of a sacrificial anode in an electrolytic cell divided by a separator, at a diamond film cathode; the anode consists of a material which is stable under electrolytic conditions; in particular it is a diamond film electrode. The catholyte comprises an organic solvent and a conducting salt.
