Preparation of α-halo-F-2-ketones and F-2-ketones via fluorination of α,α-dihalo-F-2-ketones
Fluorination of α,α-dichloro-F-2-ketones with antimony pentafluoride provided excellent yields of α-chloro-F-2-ketones and F-2-ketones regioselectively.However, fluorination of α,α-dibromo-F-2-ketones with antimony pentafluoride gave a mixture of α-bromo-F-2-ketones and F-2-ketones.
