For secondary amines (of the form R−NH−R), the longest carbon chain attached to the nitrogen atom becomes the primary name of the amine; the other chain is prefixed as an alkyl group with location prefix given as an italic N: CH 3 NHCH 2 CH 3 is N-methylethanamine.
The Geneva Nomenclature of 1892 was created as a result of many other meetings in the past, the first of which was established in 1860 by August Kekulé. Another entity called the International Association of Chemical Societies (IACS) existed, and on 1911, gave vital propositions the new one should address: [ 2 ]
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atom with a lone pair.Formally, amines are derivatives of ammonia (NH 3), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group [4] (these may respectively be called alkylamines ...

n-Butylamine is an organic compound (specifically, an amine) with the formula CH 3 (CH 2) 3 NH 2. This colourless liquid is one of the four isomeric amines of butane, the others being sec-butylamine, tert-butylamine, and isobutylamine. It is a liquid having the fishy, ammonia-like odor common to amines. The liquid acquires a yellow color upon ...
Imines are intermediates in the alkylation of amines with formic acid in the Eschweiler-Clarke reaction. A rearrangement in carbohydrate chemistry involving an imine is the Amadori rearrangement . A methylene transfer reaction of an imine by an unstabilised sulphonium ylide can give an aziridine system.
Many alkyl amines are produced industrially by the amination of alcohols using ammonia in the presence of solid acid catalysts. Illustrative is the production of tert-butylamine: NH 3 + CH 2 =C(CH 3) 2 → H 2 NC(CH 3) 3. The Ritter reaction of isobutene with hydrogen cyanide is not useful in this case because it produces too much waste. [1]
The reaction is acid catalyzed and the reaction type is nucleophilic addition of the amine to the carbonyl compound followed by transfer of a proton from nitrogen to oxygen to a stable hemiaminal or carbinolamine. With primary amines, water is lost in an elimination reaction to an imine. With aryl amines, especially stable Schiff bases are formed.
