| Abstract: | During its condensation with α-halo ketones, the hexafluoro- acetone-potassium fluoride complex behaves as a weak nucleophile and a strong base. Nucleophilic substitution produces α-perfluoroalkoxy ketones. Abstraction of a proton α to the carbonyl function leads to the formation of ether-ketones substituted by the group C(CF3)2. In some cases, hydrogen halide elimination can occur. |
