Question

Question: Predict the products of the following reactions

f.

Short answer

Answer

Step-by-step solution

Claisen ester condensation

In this sodium ethoxide is used for condensation to avoid the transesterification. Ethoxide is the base which protonate the acidic hydrogen to form $\beta$keto ester.

Formation of the product followed by alkylation

Ethoxide is used as base to form enolate ion which form keto ester on further reaction with the alkyl halide the alkylation occur means the by removal of halide ion the alkyl group attached at the alpha position to the carbonyl.

Mechanism

1. Acidic hydrogen protonated
2. Formation of the enolate ion
3. Alkylation
