diazoniumsalze
Diazoniumsalze are a class of organic compounds containing the functional group R−N₂⁺X⁻, where R is an organic group, N₂⁺ is the diazonium group, and X⁻ is an anion. They are typically formed by the reaction of a primary aromatic amine with nitrous acid (generated in situ from sodium nitrite and a strong acid) at low temperatures. This process is known as diazotization.
Diazoniumsalze are highly reactive and serve as important intermediates in organic synthesis. The diazonium group is
Another significant application is in the synthesis of azo dyes. Diazoniumsalze readily couple with electron-rich aromatic
Due to their instability, diazoniumsalze are usually prepared and used immediately in situ. They can be explosive
