Chapter 23, Problem 23.14P

Interpretation Introduction

Interpretation:

It is to be shown how to synthesize butylbenzene from benzene.

Concept introduction:

The alkyl group activates the aromatic ring toward electrophilic aromatic substitution, so with an alkyl group having been added in the first alkylation, subsequent alkylations become faster. It is often better to add an alkyl group by first acylating the ring and then reducing the C=O group to a CH₂ group.
