Chapter 21.11, Problem 21.32P

(a)

Interpretation Introduction

Interpretation:

The use of anhydride to synthesize the given compound and the reason for the preference of an anhydride over an acid chloride is to be explained.

Concept introduction:

Anhydrides undergo many of the reactions as same as acid chlorides. Anhydrides are easily converted to less reactive acid derivatives as well as they participate in the Friedel-Crafts acylation. Many reactions of anhydrides involve the loss of one of the two acid molecules as a leaving group. Anhydrides often give better yields than acetyl chloride for acetylation of alcohols.
