Selective Dimerization by Paired Electrolysis of Enol Acetate

Article abstract of DOI:10.1246/cl.1991.1661

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.
