Monofluorinated epoxides were successfully prepared through the O-cyclization reaction between α-fluorosulfoximines and ketones. The obtained fluoroepoxides were found to readily undergo an interesting ring-opening process (involving both a CF bond cleavage and another CF bond formation) in the presence of titanium tetrafluoride or pyridinium poly(hydrogen fluoride) to afford α-fluorinated ketones
