Abstract
The invention concerns a method for sulphonylating a hydroxylated organic compound. The invention concerns in particular aliphatic hydroxylated compounds and more particularly those which comprise on their aliphatic chain, an electroattractive group. The method for sulphonylating a hydroxylated organic compound is characterised in that it consists in reacting said compound, with a sulphonylating agent, in the presence of a sufficient amount of a Lewis acid.
