The title carbocations have been produced by the reaction of silver trifluoromethanesulfonate with mixed orthothioesters. Intramolecular aromatic electrophilic substitution (annulation) of the cationic intermediates proceeds readily and provides an efficient, chemoselective route for appending six-membered rings to nonactivated aromatic systems.
