The method described calls for primary and secondary alcohols to be reacted with perfluorobutane sulphonyl fluoride, or with higher homologues such as perfluorooctane sulphonyl fluoride, in the presence of 2,3 equivalents of strong organic bases and in pure organic solvents.

L'invention concerne un nouveau procédé permettant de convertir des groupes hydroxyle en composés fluorés correspondants. Selon ce procédé, on fait réagir des alcools primaires et secondaires avec du fluorure de perfluorobutanesulfonyle ou des homologues supérieurs tels que le fluorure de perfluoro-octanesulfonyle, en présence de 2 à 3 équivalents de bases organiques fortes, dans des solvants organiques absolus.
