Claisen Condensations Claisen condensations involve the enolate anion of an ester which acts as a nucleophile attacking another molecule of ester. The resulting product of this reaction is a Beta-ketoester. Draw the enolate anion which serves as the nucleophile in the reaction above. Draw the resonance structure of this enolate. Look at the mechanism of this reaction in your textbook (7^th edition), pages 773-774. What type of reaction does this resemble, S_N1,S_N2, E1, or E2? Ethanol is one of the...
