Fluorination of α,α-dichloro-F-2-ketones with antimonypentafluoride provided excellent yields of α-chloro-F-2- ketones and F-2-ketones regioselectively. However, fluorination of α,α-dibromo-F-2-ketones with antimonypentafluoride gave a mixture of α-bromo-F-2-ketones and F-2-ketones.

complexes formed from nickelcarbonyl and F-ketones in donor solvents are stable at 25 °C and decompose on heating with little or no elimination of fluoride ion. However, treatment of one such complex with iodobenzene at 25 °C resulted in benzoylation at oxygen with a concomitant loss of fluoride. Fluoroketones bearing an α-chlorine atom, on the other hand, reacted with nickelcarbonyl at moderate temperatures
