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 removing a proton from an alpha carbon with a strong base, LDA, to form an enolate ion and then adding an appropriate alkyl halide. The alkylation is a
