The effects of Lewis acid, solvent and orthothio substituent have been examined with regard to intramolecular electrophilic aromatic substitution (annulation) with bisthiocarbocations.A suspension of silver trifluoromethanesulfonate in dichloromethane, creating bis(arylthio)carbocations, was found to be the most effective for annulation of six-membered rings.
