Additions via Carbanion Intermediates

Nucleophiles can be added to acceptor-substituted alkenes. In that case, enolates and other stabilized carbanions occur as intermediates. Reactions of this type are discussed in this book only in connection with 1,4-additions of organometallic compounds (Section 10.6), or enolates (Section 13.6) to a,/J-unsaturated carbonyl and carboxyl compounds.
