Chapter 23.8, Problem 6P

Interpretation Introduction

Interpretation:

The two products that are formed in the Fries rearrangement of phenyl benzoate are to be stated.

Concept introduction:

Aryl esters react with aluminium chloride and result in the formation of hydroxy aryl ketones. This type of reaction is known as Fries rearrangement.

Aluminium chloride acts as a Lewis acid and it reacts with oxygen atom of acyl group.

The acyl group of the phenol ester migrates to the aryl ring. This rearrangement results in the formation of $ortho\text{-}$ and $para\text{-}$ substituted products.
