Amines are organic compounds derived by replacing hydrogen atoms of an ammonia molecule with alkyl/aryl groups.

Primary amines are obtained by reducing nitriles with lithium aluminium hydride (LiAlH₄) or catalytic hydrogenation. This method allows the ascent of the amine series, leading to amines with one carbon atom more than the starting amine.

The primary amines obtained through ammonolysis act as nucleophiles and can react with alkyl halides to form secondary and tertiary amines. This sequence of reactions can eventually lead to the formation of quaternary ammonium salts.

Ammonolysis involves the cleavage of the carbon-halogen (C–X) bond in alkyl or benzyl halides by ammonia, leading to the substitution of the halogen with an amino (–NH₂) group. This method is conducted in a sealed tube at 373 K and ...

Amines are obtained by reducing nitro compounds using hydrogen gas and catalysts like nickel, palladium, or platinum. The reduction with iron scrap and hydrochloric acid is preferred due to the formation of FeCl₂, which hydrolyzes to release hydrochloric acid, minimizing ...
