- In this chapter, we will study three types of Condensation reactions: Michael, Aldol and Claisen. Match the right reaction with the statements below. ● This condensation reaction takes place between two esters. The electrophile in this reaction must be an a,B-unsaturated carbonyl compound. The B-hydroxy carbonyl products of this reaction are often dehydrated to form a,B- unsaturated carbonyl products.The right-hand side of this reaction shows the product of an aldol condensation. What are the reactants missing from the left-hand side? Draw them below. 2 NaOH ? A If there aren't any reactants that would lead to these products under the reaction conditions given, just check the box under the drawing area.
