In chemistry, azide ( / ˈ eɪ z aɪ d/, AY-zyd) is a linear, polyatomic anion with the formula N − 3 and structure −N=N +=N −. It is the conjugate base of hydrazoic acid HN 3. Organic azides are organic compounds with the formula RN 3, containing the azide functional group. [1] The dominant application of azides is as a propellant in air bags. [1] Preparation [ edit ]

Azide salts can decompose with release of nitrogen gas. The decomposition temperatures of the alkali metal azides are: NaN 3 (275°C), KN 3 (355°C), RbN 3 (395°C), and CsN 3 (390°C). This method is used to produce ultrapure alkali metals: [4] 2 MN 3 heat → 2 M + 3 N 2J. H. Boyer & J. Hamer (1955). "The Acid-catalyzed Reaction of Alkyl Azides upon Carbonyl Compounds". J. Am. Chem.

Many inorganic azides can be prepared directly or indirectly from sodium azide. For example, lead azide, used in detonators, may be prepared from the metathesis reaction between lead nitrate and sodium azide. An alternative route is direct reaction of the metal with silver azide dissolved in liquid ammonia. [3] Some azides are produced by treating the carbonate salts with hydrazoic acid. In organic chemistry, the Schmidt reaction is an organic reaction in which an azide reacts with a carbonyl derivative, usually an aldehyde, ketone, or carboxylic acid, under acidic conditions to give an amine or amide, with expulsion of nitrogen. [1] [2] [3] It is named after Karl Friedrich Schmidt (1887–1971), who first reported it in 1924 by successfully converting benzophenone and hydrazoic acid to benzanilide. [4] The intramolecular reaction was not reported until 1991 [5] but has become important in the synthesis of natural products.
