(a)
Interpretation: The following given compounds prepared from cyclohexanone using an enamine intermediate.
Concept introduction: To increase the carbon chain, substituting an alkyl group on alpha carbon of a carbonyl group is called alkylation.
Alkylation is carried out by reaction of a
Acylation is carried out by reaction of a ketone with a secondary amine in the presence of an acid to form an enamine and then adding an appropriate acyl halide. The acylation is an addition reaction.
