Generated in situ, the parent allylvinyl sulfonium ion rapidly undergoes the title rearrangement to give a γ,δ-unsaturated thionium ion; a similar process appears to be involved in the reaction of phenyl vinyl sulfoxide with isobutene.

Phenyl vinylsulfoxide reacts under acylating conditions (TFA, TFAA) with isobutene to give double 'ene" alpha,beta-adduct Propene and other alkenes examined afford a beta-"ene" alkylation accompanied by trifluoroacetoxylation at the same carbon atom.
