The electrolysis of ethyl sodiomethylacetoacetate in NN-dimethylacetamide at a platinum anode gives diethyl α,α′-diacetyl-α,α′-dimethylsuccinate, 4,5-diethoxycarbonyl-3,4,5-trimethylcyclopent-2-enone and 4-ethoxycarbonyl-3,4-dimethylcyclohex-2-enone. Degradation of these products with aqueous ethanolic alkali gives a mixture of dimethylcyclohexenones and trimethylcyclopentenones; the synthesis of 2
乙基sodiomethylacetoacetate在电解NN二甲基乙酰胺在一个铂阳极给出二乙α,α'二乙酰基α,α'-丁二酸二甲酯,4,5-二乙氧基羰基-3,4,5-三甲基环己-2-烯酮和4-乙氧羰基-3,4-二甲基环己-2-烯酮。用含水乙醇碱降解这些产物,得到二甲基环己烯酮和三甲基环戊烯酮的混合物。讨论了2,3,4-三甲基环戊-2-烯酮的合成。
