for the synthesis of 2-aryl-perfluorobenzoxazoles was developed via a direct dual C–F functionalization of perfluorobenzene with arylformamide in the presence of a Fe(II)/NaH/DMSO system. Various substituted aryl formamides are tolerated giving good yields. The preliminary fluorescenceproperties (up to 99% fluorescence quantum yield of 3d) of the products and their applications in the synthesis of uniform
