It was found that (E)-vinylic sulfones preferentially afford (Z)-allylic sulfones as kinetically-controlled products by treatment with a base under mild conditions, while (Z)-vinylic sulfones give (E)-allylic sulfones.Such stereochemical relationship was

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)
