The unique molecular discriminations are observed in the Eu(III)-catalyzed reactions of saturated ketones, α,β-enones, and α,β-ynones with ketene silyl acetals and discussed in terms of the discriminating ability of the Eu-catalyst at the complexation stage.

Fe-Catalyzed Three-Component Coupling Reaction of α,β,γ,δ-Unsaturated Carbonyl Compounds and Conjugate Dienes with Alkylsilyl Peroxides and Nucleophiles
An Fe(OTf)2-catalyzed three-component coupling reaction of α,β,γ,δ-unsaturated carbonylcompounds with alkylsilyl peroxides in the presence of certain heteronucleophiles (ROH and indole) is realized under mild reaction conditions. A variety of α,β,γ,δ-diene carbonyl substrates with different substituents were successfully employable via combination with several different alkylsilyl peroxides. This
