Q24 of 30 Page 246

Suggest a route by which the following conversion can be accomplished.


i)Using Hoffmann bromamide degradation reaction we will get amine.



ii)By alkylation of the amine



Mechanism:


The nitrogen of amine acts as a nucleophile and attacks the carbon of alkyl halide as it is an electrophile. It displaces the halogen and forms a bond with carbon. Amines react through SN2 mechanism.


CH3 –Br → CH3+ + Br –
