Synthesis and some properties of 2-(polyfluoroalkyl)chroman-4-ols and 2-(polyfluoroalkyl)chroman-4-ones.

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 R-containing chromane derivatives. [ABSTRACT FROM AUTHOR]
