In organic chemistry, an aromatic amine is an organic compound consisting of an aromatic ring attached to an amine. It is a broad class of compounds that encompasses anilines, but also many more complex aromatic rings and many amine substituents beyond NH 2. Such compounds occur widely. [1]
Amine. In chemistry, amines (/ ə ˈ m iː n, ˈ æ m iː n /, [1] [2] UK also / ˈ eɪ m iː n / [3]) are compounds and functional groups that contain a basic nitrogen atom with a lone pair.Formally, amines are derivatives of ammonia (NH 3), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group [4] (these may respectively be called alkylamines ...
The reaction of converting primary aromatic amine into diazonium salt is called diazotisation. In this reaction primary aromatic amine is allowed to react with sodium nitrite and 2 moles of HCl , which is known as "ice cold mixture" because the temperature for the reaction was as low as 0.5 °C.

The reaction mechanism [2] begins with an imine condensation of a primary aromatic amine and formaldehyde. Once the imine is produced, it reacts with phenol in the presence of water to yield an α-aminobenzylphenol. An electron pushing mechanism for the Betti Reaction.
In organic chemistry, the Mannich reaction is a three-component organic reaction that involves the amino alkylation of an acidic proton next to a carbonyl (C=O) functional group by formaldehyde (H−CHO) and a primary or secondary amine (−NH 2) or ammonia (NH 3). [1] The final product is a β-amino-carbonyl compound also known as a Mannich base.
Another common example is the reaction of a primary amine or secondary amine with a carboxylic acid or with a carboxylic acid derivative to form an amide. This reaction is widely used, especially in the synthesis of peptides. On the simple addition of an amine to a carboxylic acid, a salt of the organic acid and base is obtained.
