Reduction of 2-(polyfluoroalkyl)chromones by sodium borohydride in methanol gives cis-2-(polyfluoroalkyl)chroman-4-ols in high yields, which are easily oxidized by chromic acid to 2-(polyfluoroalkyl)chroman-4-ones. The latter are of interest as the starting materials for the preparation of novel RF-containing chromane derivatives.
