Abstract

The invention comprises the compounds Rf(CH2)mOH, where Rf is a perfluoroalkyl radical having 3-12 carbon atoms and m is 3-12. These compounds may be prepared by the desulphonylative addition of a perfluoroalkane sulphonyl halide to a terminally unsaturated alcohol, esterified alcohol, or carboxylic acid, followed by reductive dehalogenation to replace halogen by chlorine, and hydrolysis if an esterified alcohol was used or reduction if an acid was used. In Examples, (1) C8F17SO2Cl is reacted with 4-pentenoic acid to give 4-chloro-5-(perfluorooctyl)-pentanoic acid, which is hydrogenated to 5-perfluorooctyl pentanoic acid, and this is reduced to 5-perfluorooctyl-pentanol; (2) C8F17SO2Cl is reacted with alkyl acetate to give 2-chloro-3-(perfluorooctyl) propyl acetate, which is dehydrohalogenated to 3-(perfluorooctyl) alkyl alcohol, and this is reduced to 3-(perfluorooctyl) propanol; (3) ethyl perfluorobutyrate is condensed with methyl acetate to give C3F7COCH2COOCH3, this is reduced to C3F7CHOHCH2COOCH3, which is dehydrated to C3F7CH:CHCOOCH3; this is hydrogenated to the saturated ester, which is reduced to C3F7(CH2)3OH.
