| 摘要 |
The invention relates to a method for producing γ-hydroxycarboxylic esters and γ-lactones, which are suitable as aromatic substances, by electrochemical reductive cross-coupling of α,β-unsaturated esters with carbonyl compounds in an undivided electrolytic cell, said cell having a cathode that consists of lead, lead alloys, cadmium, cadmium alloys, mercury, steel, glassy carbon or boron-doped diamonds, and using an alkaline aqueous electrolyte comprising a conducting salt which suppresses cathodic hydrogen formation. |
