Abstract3,3-Dichloropentane-2,4-dione reacts with aromatic aldehydes under the conditions of Darzens reaction to give 4-acetoxy-4-aryl-3,3-dichlorobutan-2-ones, the products of insertion into the σ-C-C bond. The reaction of ethyl dichloroacetylacetate with benzaldehyde yields a derivative of tricyclo[5.1.0.03,5]octane, rather than 2,6-bis(1′-chlorobenzylidene)cyclohexane-1,4-dione, as the by-product
摘要 3,3-Dichloropentane-2,4-dione 在 Darzens 反应条件下与芳香醛反应生成 4-acetoxy-4-aryl-3,3-dichlorobutan-2-ones,插入 σ-CC 的产物键。二氯乙酰乙酸乙酯与苯甲醛反应生成三环[5.1.0.03,5]辛烷的衍生物,而不是副产物2,6-双(1'-氯亚苄基)环己烷-1,4-二酮。
