Primary aromatic amines yield diazonium ions in a solution of sodium nitrite. Upon heating this solution with copper(I) chloride, the diazonium group is replaced by -Cl. This is a comparatively easy method to make aryl halides as the gaseous product can be separated easily from aryl halide. When an iodide is to be made, copper chloride is not ...
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 Gabriel synthesis is a chemical reaction that transforms primary alkyl halides into primary amines.Traditionally, the reaction uses potassium phthalimide. [1] [2] [3] The reaction is named after the German chemist Siegmund Gabriel.
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]
In organic chemistry, hydroamination is the addition of an N−H bond of an amine across a carbon-carbon multiple bond of an alkene, alkyne, diene, or allene. [1] In the ideal case, hydroamination is atom economical and green. [2] Amines are common in fine-chemical, pharmaceutical, and agricultural industries.

Reductive amination (also known as reductive alkylation) is a form of amination that converts a carbonyl group to an amine via an intermediate imine. The carbonyl group is most commonly a ketone or an aldehyde. It is a common method to make amines and is widely used in green chemistry since it can be done catalytically in one-pot under
