Sulfonylation of arenes with sulfonamides

In the presence of triflic anhydride, sulfonylation of arenes with sulfonamides proceeded smoothly in Cl2CHCHCl2 at 80-140 °C, which gave rise to the desired products in good to excellent yields.

Lewis Acid Catalyzed Sulphenylation of Methylbenzene by p-Chlorobenzenesulphenyl Chloride

The Lewis acid catalyzed reactions of benzene and several methylbenzenes with p-chlorobenzenesulphenyl chloride are reported.The products include sulphenylated arenes - p-chlorophenyl aryl sulphides, bis(p-chlorophenylthio)arenes, chloro(p-chlorophenylthio)arenes - as well as chlorinated arenes and bis(p-chlorophenyl)disulphides.The disulphide: combined sulphenylation products ratio for each arene, e.g. 27:73 (for benzene) and 12:86 (for mesitylene), shows only a small variation when compared to the large differences in reactivity of the arenes towards electrophilic reagents.
