Chapter 23, Problem 23.51P

Interpretation Introduction

Interpretation:

Synthesis of the given tertiary amine has to be shown using the given retrosynthetic analysis.

Concept Introduction:

Friedel-Crafts Acylation: This Lewis acid-catalyzed electrophilic aromatic substitution is the reaction between arenes and acyl chlorides or anhydrides for the synthesis of monoacylated compound. The products are deactivated, as well as do not undergo a second substitution.

Bromination: In bromination reaction, hydrogen atom of a molecule is replaced by a bromine atom.

${\text{S}}_{\text{N}}2$Reaction: It is a nucleophilic substitution reaction in which the rate determining step depends on both of the molecules involved. The bond making and the bond breaking process happens simultaneously in this reaction.

Structure of the substrate plays major role in the reactivity of ${\text{S}}_{\text{N}}2$ reaction. If the substrate is more substituted then the rate of the reaction will becomes slower. Since the mechanism of ${\text{S}}_{\text{N}}2$ reaction proceeds through backside attack on the substrate, it depends on steric factor that if more groups attached near the leaving group the reactivity becomes slower.
