Arenediazonium salt

Definition

Arenediazonium salts are a group of organic compounds formed by the reaction of an aromatic amine with nitrous acid, leading to the replacement of the amine's nitrogen-hydrogen group with a nitrogen double-bonded to another nitrogen atom (N2+) that is then paired with an anion. These salts are key intermediates in the synthesis of various aromatic compounds, including dyes, through reactions such as azo coupling and Sandmeyer reactions.

Aromatic Amine: An organic compound consisting of an aromatic ring attached to an amine group; it serves as the starting material for producing arenediazonium salts.

Azo Coupling Reaction: A chemical reaction between a diazonium compound and another aromatic compound that results in the formation of an azo bond (-N=N-), commonly used to synthesize azo dyes.

Sandmeyer Reaction:

A chemical reaction where arenediazonium salts react with copper(I) chloride or bromide to form aromatic halides, facilitating substitutions that introduce different functional groups into aromatic rings
