Conversion of vinyl sulfones to regiospecifically functionalized trisubstituted olefins
Conjugate-addition of phenyldimethylsilyllithium (or cuprate) to vinyl sulfones followed by in situ alkylation of the α-sulfonyl anion provides α-alkylated β-silyl sulfones. Treatment of these materials with fluoride provides trisubstituted olefins via th
