WebDiazonium salts are important synthetic intermediates that can undergo coupling reactions to form azo dyes and electrophilic substitution reactions to introduce functional groups . Uses of the reaction [ edit] Aromatic azo compounds tend to be brightly colored due to the extended conjugated systems. Many are used as dyes (see azo dye ). [2] Webdiazonium salt, any of a class of organic compounds that have the molecular structure in which R is an atomic grouping formed by removal of a hydrogen atom from an organic compound. Diazonium salts are usually prepared by the reaction (diazotization) of primary amines with nitrous acid; their most striking property is their instability.
