Sodium azide is a versatile precursor to other inorganic azide compounds, e.g., lead azide and silver azide, which are used in detonators as primary explosives. These azides are significantly more sensitive to premature detonation than sodium azide and thus have limited applications. Lead and silver azide can be made via double displacement ...
Main group azido compounds are chemical compounds consisting of azide, N 3-bonded to a main group element. [1] [2]Azido compounds are often shock sensitive.Their sensitivity correlates with the amount of ionic or covalent character the azide-element bond has, with ionic character being far more stable than covalent character. [3]
Popular synthetic routes to homoleptic azido compounds. There are several general routes and strategies employed when synthesizing homoleptic azido compounds. Salt metathesis between an azide salt like sodium azide or silver azide and the metal chloride is how a lot of the earlier azides were prepared. [7]
Pentaazidoiron (III) ion [Fe(N 3) 5] 2-can be made by treating iron(III) salts with sodium azide. [ 26 ] [ 27 ] An iron azide reagent can be generated in situ . [ 28 ] NaN 3 and iron (III) sulfate Fe 2 (SO 4 ) 3 are combined in methanol and added to an organoborane followed by slow addition of 30% hydrogen peroxide, presumably forming Fe(N 3 ) 3 .
As hydrazoic acid, the protonated form of the azide anion, has a very low reduction potential E° red = -3,09 volt, and is even a stronger reductant than lithium (E° red = -3.04 volt), dry solid sodium azide can be added to molten metallic sodium (E° red = -2,71 volt) under strict anoxic conditions (e.g., in a special anaerobic glovebox with ...
In the Curtius rearrangement, sodium azide and an acyl chloride are combined to quantitatively generate the acyl azide intermediate, and the rest of the reaction takes place under neutral conditions.) The carboxylic acid Schmidt reaction starts with acylium ion 1 obtained from protonation and loss of water.

The acyl azide is usually made from the reaction of acid chlorides or anhydrides [6] with sodium azide [7] or trimethylsilyl azide. [8] Acyl azides are also obtained from treating acylhydrazines with nitrous acid. [9] Alternatively, the acyl azide can be formed by the direct reaction of a carboxylic acid with diphenylphosphoryl azide (DPPA ...
