Carbon–carbon bond formation between α-halogenoketones and aldehydes promoted by cerium(III) iodide or cerium(III) chloride–sodium iodide
Abstract
α-Halogenoketones react with aldehydes to form α,β-unsaturated ketones accompanied by dehalogenation in the presence of cerium(III) iodide, but use of cerium(III) chloride–sodium iodide results in the formation of β-keto alcohols.
