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]
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.
Primary (1°) amines—Primary amines arise when one of three hydrogen atoms in ammonia is replaced by an alkyl or aromatic group. Important primary alkyl amines include methylamine , most amino acids , and the buffering agent tris , while primary aromatic amines include aniline .

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.
Amine alkylation (amino-dehalogenation) is a type of organic reaction between an alkyl halide and ammonia or an amine. [1] The reaction is called nucleophilic aliphatic substitution (of the halide), and the reaction product is a higher substituted amine. The method is widely used in the laboratory, but less so industrially, where alcohols are ...
The Hinsberg reaction is a chemical test for the detection of primary, secondary and tertiary amines.The reaction was first described by Oscar Hinsberg in 1890. [1] [2] In this test, the amine is shaken well with the Hinsberg reagent (benzenesulfonyl chloride) in the presence of aqueous alkali (either KOH or NaOH).
