Chapter 17, Problem 17.10P

Interpretation Introduction

(a)

Interpretation:

The major organic product is to be predicted in the given reaction.

Concept introduction:

${\text{LiAlH}}_{\text{4}}$ is a strong reducing agent and source of ${\text{H}}^{\text{-}}$ nucleophile. ${\text{LiAlH}}_{\text{4}}$ is the reducing agent that reduces the nitrile or imine into the amines. In these reactions, first, the addition of ${\text{H}}^{\text{-}}$ is followed by protonation to form a corresponding amine product with reduction of the reactants. ${\text{LiAlH}}_{\text{4}}$ reduction must take place in a solvent that has no acidic protons, such as ether.
