Chapter 22, Problem 22.2P

Interpretation Introduction

Interpretation:

Synthetic approach to synthesize an aromatic halogenation reaction.

Concept introduction:

This is a type of aromatic halogenation reaction. In this reaction Bromine, Br_2, does not react with benzene under normal conditions, but bromination produces bromobenzene in the presence of Fe or FeBr₃ where FeBr₃ acts as a Lewis acid. The product of an aromatic halogenation, an aryl halide, could be the desired target in the synthesis. An aryl halide could be a useful synthetic intermediate such as in the production of a Grignard reagent.
