Sulfonylation reactions are one of the most important groups of aromatic electrophilic substitutions. 1 The sulfonyl group is a widely used synthon for synthetic organic chemists, 2 and sulfones have many industrial applications. 3 In Friedel-Crafts (FC) acylation and sulfonylation, a consequence of the complexation of the Lewis acid with the reaction product implies that a stoichiometric amount of the activator is often required. However, some ...
