Three-membered cyclic sulfones undergo substitution on treatment with base-electrophile mixtures, such as LDA-Me3SiCl and tBu-P4-phosphazene base-PhCHO, to give either substituted episulfones or the corresponding alkenes following loss of SO2-In the absence of Me3SiCl, reaction of episulfones with LDA results in ring-opening to give alkenyl sulfinate intermediates, which can be alkylated to give (E)-alkenyl sulfone products in stereoselective fashion.
