A method for the preparation of α-substituted ω-dihydroperluoroalkane derivatives of the general formula H(CF2 CF2)n R wherein R=H or COOH, and n=1-10 is characterized by oxidizing α, α, ω-trihydroperfluoroalcohols with an oxygen gas or an oxygen-containing gas in the presence of a homogeneous copper catalyst and an alkaline agent in an organic solvent with subsequent isolation of the desired product.

Dielectric and refractive index increments at 25°C are reported for some α,ω-dihydroperfluoroalkanes and α-hydro-ω-iodoperfluoroalkanes in benzene and CCl4. Similar measurements on perfluorocyclohexane and perfluoro-n-hexane are used to deduce effective atomic polarizations for fluorocarbons in solution. The dipole moments obtained lead to a somewhat smaller characteristic ratio for the perfluoroalkane chain than had earlier been estimated by Bates and Stockmayer.
