The intramolecular displacement of aryl ethyl sulphonium by carbanions stabilised by two sulphonyl groups has been studied.Rates of cyclisation of three-, four- and five-membered rings follow the same trend observed in the analogous displacement of halides.The effects of substituents on the leaving group show that, in the series considered, variations in the extent of bond cleavage to the leaving group are small.
