Question

write preparation of different Amine​

Answer 1

Primary amines can be synthesized by alkylation of ammonia. A large excess of ammonia is used if the primary amine is the desired product. Haloalkanes react with amines to give a corresponding alkyl-substituted amine, with the release of a halogen acid.

Answer 2

Answer:

You can best prepare a primary amine from its alkylazide by reduction or by the Gabriel synthesis. In the Gabriel synthesis, potassium phthalimide is reacted with an alkyl halide to produce an N‐alkyl phthalimide. This N‐alkyl phthalimide can be hydrolyzed by aqueous acids or bases into the primary amines.
