Process for the preparation of a 4-butanolide compound |
| 摘要 |
The electrolytic reduction of a mixture of an acrylic ester and an aldehyde in the form of an aqueous emulsion in the presence of at least one phase-transfer catalyst using a lead or lead alloy cathode has been found to be very effective for preparing a 4-butanolide compound simply and safely in high yield with a high current efficiency.
