Chapter 23.9, Problem 9P

Interpretation Introduction

Interpretation:

The chemical equations expressing each of the given reactions are to be written.

Concept Introduction:

$o$-acylation of phenols takes place when they react with an acyl halide.

$o$-acylation of phenols also occurs when they react with acid anhydrides.

The reactivity of acid anhydrides is less than that of acyl halides.

The esterification of phenolic oxygen results in the formation of an ester via $o$-acylation.
