  • One-Step Preparation of Symmetrical 1,4-Diketones from α-Halo Ketones in the Presence of Zn-I<sub>2</sub> as a Condensation Agent
    作者:Mustafa Ceylan、M. Gürdere、Yakup Budak、Cavit Kazaz、Hasan Seçen
    DOI:10.1055/s-2004-829118
    日期:——
    Eleven 1,4-diphenylbutane-1,4-diones have been prepared in one step from the corresponding α-halo acetophenones under the action of Zn-I2 as a condensation agent with moderate to high yields. The mechanistic pathway of the reaction can be explained by the Wurtz-like self-condensation of α-halo ketones. Similarly, 3-chloropentane-2,4-dione gave 3,4-diacetylhexane-2,5-dione, a Wurtz-like condensation product.
    在 Zn-I2 作为缩合剂的作用下,11 种 1,4- 二苯基丁烷-1,4-二酮从相应的 δ-卤代苯乙酮一步制备得到,产率从中等到较高不等。该反应的机理途径可以用δ-卤代酮的类似于 Wurtz 的自缩合来解释。同样,3-氯戊烷-2,4-二酮也生成了 3,4-二乙酰基己烷-2,5-二酮,这是一种类似于 Wurtz 的缩合产物。
