Electrolysis of enol esters of cyclic ketones possessing an alkyl group at the α-position using graphite carbon electrodes (EGM62 or EG10 : Nippon Carbon Co. Ltd.) brought about selective dimerization at the β-position of the ketones to give the corresponding 1,6-diketones in good to moderate yields. It was found that initial anodic formation of α,β-unsaturated ketones was successively followed by cathodic hydrodimerization (paired electrolysis) in an undivided cell.
使用石墨碳电极(
EGM62或
EG10:日本碳业股份有限公司)对具有α位置烷基取代基的环酮的烯醇酯进行电解,成功地在酮的β位置实现了选择性二聚,获得了相应的1,6-二酮,得率为良好至中等。研究发现,初始阳极形成α,β-不饱和酮后,随之在未分隔的电解池中发生了阴极的
水合二聚反应(配对电解)。
