Abstract:
The subject of the present invention is a method for the sulphonylation of a hydroxylated organic compound. The invention relates more particularly to a method for the trifluoromethanesulphonylation of a hydroxylated organic compound. The invention is especially intended for perfluorinated aliphatic hydroxylated compounds. The method of the invention for the sulphonylation of a hydroxylated organic compound is characterized in that it comprises reacting said compound with a sulphonylation agent in an organic medium and in the presence of a heterogeneous inorganic base.
