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atom with a lone pair.Formally, amines are derivatives of ammonia (NH 3), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group [4] (these may respectively be called alkylamines ...
Consisting of a phenyl group (−C 6 H 5) attached to an amino group (−NH 2), aniline is the simplest aromatic amine. It is an industrially significant commodity chemical, as well as a versatile starting material for fine chemical synthesis. Its main use is in the manufacture of precursors to polyurethane, dyes, and other industrial chemicals.
The Betti reaction is a chemical addition reaction of aldehydes, primary aromatic amines and phenols producing α-aminobenzylphenols. Overview of the Betti reaction. The Betti reaction is a special case of the Mannich reaction.
Heteroarenes are aromatic compounds, where at least one methine or vinylene (-C= or -CH=CH-) group is replaced by a heteroatom: oxygen, nitrogen, or sulfur. [3] Examples of non-benzene compounds with aromatic properties are furan, a heterocyclic compound with a five-membered ring that includes a single oxygen atom, and pyridine, a heterocyclic compound with a six-membered ring containing one ...
The imine is often generated in situ from an amine and formaldehyde.An example is the reaction of cyclopentadiene with benzylamine to an aza norbornene. [9]The catalytic cycle starts with the reactions of the aromatic amine with formaldehyde to the imine and the reaction of the ketone with proline to the diene.
Triethylenetetramine (TETA and trien), also known as trientine when used medically, is an organic compound with the formula [CH 2 NHCH 2 CH 2 NH 2] 2.The pure free base is a colorless oily liquid, but, like many amines, older samples assume a yellowish color due to impurities resulting from air oxidation.
