Chapter 23.SE, Problem 58AP
Interpretation Introduction

a) CH3CO2Et + CH3CH2CO2Et

Interpretation:

The structures of the possible products, indicating predominant product if any, when ethylacetate and ethyl propionate undergo Claisen condensation reaction are to be given.

Concept introduction:

The Claisen condensation reaction involves a reversible condensation between two molecules of an ester that has α-hydrogen atoms in the presence of one equivalent of a base like sodium ethoxide. The product obtained is a β-keto ester. In the reaction an alcohol molecule is eliminated and the product has an acyl group of one of the reactant molecule attached to the α-carbon of the second molecule.

To give:

The structures of the possible products, indicating predominant product if any, when ethylacetate and ethyl propionate undergo Claisen condensation reaction.

Interpretation Introduction

b) C6H5CO2Et + C6H5CH2CO2Et

Interpretation:

The structures of the possible products, indicating predominant product if any, when ethylbenzoyate and ethylphenylacetate undergo Claisen condensation reaction are to be given.

Concept introduction:
