Abstract
2-Polyfluoroalkylchromones react with 2-aminoethanol at room temperature to give either 3-(2-hydroxyethylamino)-1-(2-hydroxyphenyl)-3-polyfluoroalkylp rop-2-en-1-ones [R-F = CF2H, CF3, (CF2)(2)OCF3 or (CF2)(3)CF3] or N-(2-hydr oxyethyl)-2-polyfluoroalkyl-4H-chromene-4-imines [R-F = (CF2)(2)H or C2F5].
