Carbon-Carbon Bond Formation between α-Halogenoketones and Aldehydes Promoted by Cerium(III) Iodide or Cerium(III) Chloride-Sodium Iodide

Article abstract of DOI:10.1039/c39850000777

α-Halogenoketones react with aldehydes to form α,β-unsaturated ketones accompanied by dehalogenation in the presence of cerium(III) iodide, but the use of cerium(III) chloride-sodium iodide results in the formation of β-keto alcohols.
