Question
Chapter 22.12, Problem 22.35P
Interpretation Introduction
Interpretation:
A mechanism for the claisen condensation of ethyl isobutyrate is to be proposed and an explanation corresponding to a poor yield in this reaction is to be explained.
Concept introduction:
In the claisen-ester condensation, nucleophilic acyl substitution takes place on an ester. The enolate ion acts as a nucleophile. It attacks the carbonyl carbon to form a tetrahedral intermediate. Acidity of beta-keto ester products is higher than simple
