The regioselective reaction of coumarins 1 with bis(perfluo‐roalkanoyl) peroxides affords 3‐(perfluoroalkyl)coumarins 2 in moderate yields. The absorption and emission maxima of coumarins 2 show bathochromic shifts compared with the 3‐unsubstituted coumarins. The fluorescence intensities of 3‐(perfluoroalkyl)coumarins 2 are smaller than those of the 3‐unsubstituted ones. However, the photostabilities of coumarins 2 are higher than those of the 3‐unsubstituted ones.
