(a)
Interpretation:
The curved arrow mechanism for the given rearrangement reaction is to be shown.
Concept Introduction:
Benzylic protons are very acidic in nature as the conjugate base formed by the acid is resonance stabilized. Even a mild base can also abstract hydrogen ion. Intramolecular nucleophilic addition reaction takes place in those compounds in which nucleophile and electrophile both are present in the same compound.
(b)
Interpretation:
The curved arrow mechanism for the given rearrangement reaction is to be shown.
Concept Introduction:
Bromosuccinimide is a source of bromine radical. It can undergo various reactions. Nucleophilic addition reaction uses a nucleophile such as hydroxide ion which attacks at the electrophilic centre of the given compound to form nucleophilic addition product.
(c)
Interpretation:
The curved arrow mechanism for the given rearrangement reaction is to be shown.
Concept Introduction:
Acyl azide is heated in an inert solvent to form isocyanate with loss of nitrogen as by product. This reaction is known as Curtius rearrangement reaction. Isocyanate product of the rearrangement can be converted into amine by hydration in either an acid or base.
