A number of α-seleno- and α-thio-substituted sulphones have been prepared, and subsequently reacted with allyltrimethylsilane, using EtAlCl2 as Lewis acid, to give homoallylic selenides or sulphides respectively. Someunsaturated substrates underwent an alternative cyclisation reaction to give substituted cyclohexane products, whereas in one case the use of a trimethylsilyloxydiene in place of allyltrimethylsilane
