Interpretation Introduction

(d)

Interpretation:

The curved-arrow mechanism for the given reaction has to be predicted.

Concept introduction:

The rearrangement in which acyl azides (RCO−N3) undergoes a reaction to form the amines is known as Curtius rearrangement. The acyls azide is heated in benzene or toluene, inert solvent, which results in a loss of nitrogen to form isocyanate (R−N=C=O). The acid or base hydrolysis converts the isocyanate products into amines.
