Abstract

We wish to report an extremely rapid and efficient method for the synthesis of small quantities of sulfonyl fluorides from the corresponding sulfonyl chlorides by ion exchange chromatography. The technique is characterized by high yields (82-94%, starting with 1 g of aromatic sulfonyl chloride) and pure products which are easily isolated by evaporation of the solvent and need no recrystallization.
