A reagent is a substance added in the reaction to form the product from the reaction, which means they are used to complete the chemical reactions.

On the reaction of enamine with base, the formation of enolate occurs, followed by the reaction with acyl chloride formation of the acylated product occur that is di carbonyl product is formed.

As ketone reactant is given, which is first converted to the enamine on reacting with the ${\mathrm{Et}}_2\mathrm{NH}$followed by the reaction by reacting with the acyl chloride forming iminium salt as an intermediate which on hydrolysis form the dicarbonyl product which is required

The reaction between carbonyl compound and diethylamine results in the formation of enamine. Finally, the acylation reaction occurs, which leads to the formation of the required product.

The reaction followed as follows:

Enamine acylation
