5-dichloropenta-2,4-dien-1-ones with ethyl acetoacetate in the presence of EtONa give ethyl 4-aryl-6-(2,2-dichlorovinyl)-4-hydroxy-2-oxocyclohexane-carboxylates. The structures of the reaction products were confirmed by1H and13C NMR spectroscopy and by X-ray diffraction analysis.
1-芳基-5,5-二氯戊基-2,4-二烯-1-酮与乙酰乙酸乙酯在 EtONa 存在下反应得到 4-芳基-6-(2,2-二氯乙烯基)-4-羟基- 2-氧代环己烷-羧酸盐。反应产物的结构经 1 H 和 13 C NMR 光谱和X-射线衍射分析证实。
