Chapter 13, Problem 39P

Interpretation Introduction

Interpretation:

The structure for the expected product for each of the given compounds through an intramolecular Friedel-Craft acylation reaction that yield a cyclic ketone is to be written.

Concept introduction:

In Friedel-Crafts acylation, to yield aryl ketones, acyl halides are used.

In the intramolecular Friedel-Craft acylation, the electrophile and nucleophile present on the same molecule, resulting in the formation of a ring.

The electron releasing effect of the methoxy group attached to benzene ring makes the ring electron rich.
