Chapter 16.8, Problem 32P

(a)

Interpretation Introduction

Interpretation:

The mechanisms for the following reactions should be determined.

  1. 1. The acid-base catalyzed hydrolysis of an imine to a carbonyl compound and a primary amine.
  2. 2. The acid-base catalyzed hydrolysis of an enamine to a carbonyl compounds and a secondary amine.

Concept introduction:

The chemical compound containing carbon and nitrogen double bond is known as imine.

Enamine is derived by the condensation of an aldehyde or ketone with secondary amine.
