Conjugate additions reactions between organocopper reagents and α,β-unsaturated carbonyl compounds are now well established synthetic procedures. This article reviews reactions in which the intermediate enolates are trapped with electrophilic reagents to give β-substituted enol derivatives or α,β-disubstituted ketones. The synthetic potential of these products is highlighted. 1. Introduction: Scope and Limitations 2. Silylation and Related O-Enolate Trapping Reactions 3. Enolate Acylation 4. Enolate Alkylation 5.
