A synthetic method was developed for the preparation of vinylsulfides and vinylamines from arylalkynyl phenyl sulfides and sulfonamides. Under mild conditions, a catalyticintramolecularhydroarylation reaction was carried out in the presence of FeCl3 and AgOTf (OTf = trifluoromethanesulfonate) in 1,2-dichloroethane. A variety of 1,2-dihydronaphthalenes, 2H-chromenes, and 1,2-dihydroquinolines containing
