Abstract
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.
