The effects of Lewis acid, solvent and orthothio substituent have been examined with regard to intramol. electrophilic aromatic substitution 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. E.g., o-phenylene trithiocarbonate was condensed with 3-MeOC6H4(CH2)3I to give 2-[3-(3-methoxyphenyl)propyl]-2-methylthio-1,3-benzodithiole which was subject to intramol. aromatic substitution to give 6-methoxy-1-tetralone.
