A one‐pot cascade synthesis of perfluoroaryl oxiranes 2 by the arylative epoxidation 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.
