What is the primary product formed in a crossed Claisen condensation?
Understand the Problem
The question is asking about the primary product of a crossed Claisen condensation reaction, which is a specific type of organic reaction involving the reaction of esters with enolate ions. We need to identify the correct product among the provided options.
Answer
Beta-keto ester
The primary product formed in a crossed Claisen condensation is a beta-keto ester.
Answer for screen readers
The primary product formed in a crossed Claisen condensation is a beta-keto ester.
More Information
In a crossed Claisen condensation, the enolate ion of one ester acts as a nucleophile and reacts with a different ester, which ideally should be non-enolizable, resulting in the formation of a beta-keto ester.
Tips
Assuming that both reactants are capable of forming enolates can lead to predicting wrong side products.
