α-Pentafluoropropionylation of Ketones and Aldehydes Using Hexafluoropropene Oxide. A Facile Synthesis of Fluorinated 1,3-Diketones

Article abstract of DOI:10.1246/bcsj.55.3345

Hexafluoropropene oxide reacts smoothly with morpholine enamines from ketones and aldehydes at 0 deg 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.
