First Examples of Episulfone Substitution Reactions via .alpha.-Sulfonyl Carbanion Intermediates
摘要:
Three-membered cyclic sulfones (episulfones) undergo substitution on treatment with base-electrophile mixtures, such as LDA-Me(3)SiCl and tBu-P4-phosphazene base-PhCHO, to give either substituted episulfones or the corresponding alkenes following loss of SO2.
