The readily available 1-alkoxyalkyl and 1-alkylthioalkyl sulfones display electrophilic behavior when lithiated.For example, both react regioselectively with lithiated alkyl sulfones to give enol ethers and vinyl sulfides, respectively.A series of methyl and tert-butyl enol ethers and vinyl sulfides have been prepared. - Keywords: sulfones / alkoxyalkyl sulfones / carbenoids / enol ethers / heterosubstituted carbanions / alkylthioalkyl sulfones / vinyl sulfides

A p-tolylsulfonyl group undergoes a SiO2-catalyzed 1,3-rearrangement in a sulfenylated allylic system and this rearrangement can be utylized in novel and convenient syntheses of α,β-unsaturated ketones 6 using 3-(methylthio)-2-propenyl p-tolyl sulfone (1)
