Aromatic polyfluoro-compounds. Part LV. Preparation and reactions of some polyfluoro(alkylbenzenes)

Abstract

Perfluoro-n-butyl-, -n-octyl-, and ω-H-n-pentyl-benzenes have been prepared from pentafluorophenylmagnesium bromide by reaction with the corresponding aldehyde, followed by oxidation of the resulting alcohol to the ketone, which in turn has been treated with sulphur tetrafluoride. Some nucleophilic substitution reactions of these compounds and perfluoro-n-propylbenzene are described. The possibility of the use of some of the products as surfactants is discussed.
