Abstract

Cerium(III) chloride heptahydrate in the presence of sodium iodide catalyses the Michael addition of 1,3-dicarbonyl compounds to α,β-unsaturated ketones and α,β-unsaturated aldehydes with extraordinary efficiency. The very mild conditions allow high chemoselectivity as shown by thye absence of the typical side reactions.The catalyst system can be easily separated from the reaction mixture and it can be reused without an apprecaible loss of activity.
