Question
Chapter 16.SE, Problem 44MP
Interpretation Introduction
Interpretation:
A mechanism for the Smiles rearrangement reaction shown is to be given.
Concept introduction:
Smiles rearrangement is initiated by the nucleophilic attack of the lone pair of electrons on the N of the amino group on a carbon in the pyridine ring (made electron deficient by the electron attracting nitro group and electronegative N and O atoms). The cleavage of the five member ring formed and subsequent exchange of H+ will lead to the formation of the rearranged product.
To propose:
A mechanism for the Smiles rearrangement reaction shown.
