Chapter 23, Problem 23.19P

Interpretation Introduction

(a)

Interpretation:

The synthesis of the quaternary ammonium salt ${\left({\text{CH}}_{\text{3}}\right)}_{\text{3}}\stackrel{\text{+}}{\text{N}}{\text{CH}}_{\text{2}}{\text{PhBr}}^{-}$ from dimethylamine and any other reagents is to be predicted.

Concept introduction:

The quaternary compound is formed by the process of reductive amination. There is conversion of amine into imine. The imine is reduced to new amine. In the process of reductive amination the reduction of amine takes place with the gain of electrons by the given compound.
