Chapter 22, Problem 22.64P

Interpretation Introduction

Interpretation:

By using the same reaction condition mentioned in the problem $\text{22}\text{.35}$, the structure of the product for the given reaction is to be drawn.

Concept introduction:

The reaction mentioned in the problem $\text{22}\text{.35}$ is Friedel-crafts reaction. In which benzene is reacted with ${\text{SCl}}_{\text{2}}$ in the presence of Lewis acid ${\text{AlCl}}_{\text{3}}$ results in the formation of Diphenyl sulfide.

The reaction of diphenyl ether with ${\text{SCl}}_{\text{2}}$ in presence of Lewis acid ${\text{AlCl}}_{\text{3}}$ represents the Friedel-crafts reaction that is an aromatic electrophilic substitution reaction.

To get the six carbon signals in the product of the given reaction the presence of symmetry is must and this symmetry is achieved when substitution takes place on both rings at ortho position to the oxygen.
