A one‐pot cascade synthesis of perfluoroaryl oxiranes 2 by the arylativeepoxidation of enolizable ketones 1 with bromopentafluorobenzene (PFPBr) and derivatives (3) is reported. PFPBr is utilized as an equivalent of Br+ and PFP− in this highly efficient, easily scaled‐up, diastereoselective epoxidation reaction, which produces synthetically useful polyfluoroaryl oxiranes.
