Hexafluoropropene oxide reacts smoothly with morpholine enamines from ketones and aldehydes at 0 °C to room temperature in anhydrous THF to give pentafluorinated 1,3-diketones in good yields. The keto-enol equilibrium in the products is generally in favor of their enol form.
在 0 °C 至室温下,六氟氧化丙烯与来自酮和醛的吗啉烯胺在无水 THF 中顺利反应,以良好的收率得到五氟化 1,3-二酮。产物中的酮-烯醇平衡通常有利于它们的烯醇形式。
