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]
Azides of Sn(II) exist in the form of salts of [Sn(N 3) 3] −. Like the analogous germanates, they are very sensitive compounds. [24] They tend to dimerize. Lead azide is one of the most studied azides owing to its use as a primary explosive. [1] Uniquely it is the only group 14 azide that is more prevalent in its divalent Pb 2+ form. The α ...
The azide functional group can be shown by two resonance structures. An organic azide is an organic compound that contains an azide (– N 3) functional group. [1] Because of the hazards associated with their use, few azides are used commercially although they exhibit interesting reactivity for researchers.
Two arrangements are known: a linear form with double bonds and charge transfer, and a cyclic form. Both forms are highly unstable, though the linear form is the more stable of the two. [ 1 ] More-stable derivatives exist, such as when it acts as a ligand , and it may participate in azido nitration , which is a reaction between sodium azide and ...
In the reaction above [4] azide 2 reacts neatly with alkyne 1 to afford the product triazole as a mixture of 1,4-adduct (3a) and 1,5-adduct (3b) at 98 °C in 18 hours. The standard 1,3-cycloaddition between an azide 1,3-dipole and an alkene as dipolarophile has largely been ignored due to lack of reactivity as a result of electron-poor olefins ...
In chemistry, the pentazenium cation (also known as pentanitrogen) is a positively-charged polyatomic ion with the chemical formula N + 5 and structure N−N−N−N−N.Together with solid nitrogen polymers and the azide anion, it is one of only three poly-nitrogen species obtained in bulk quantities.
In chemistry, a nitride is a chemical compound of nitrogen.Nitrides can be inorganic or organic, ionic or covalent.The nitride anion, N 3-ion, is very elusive but compounds of nitride are numerous, although rarely naturally occurring.
DPPA undergoes pseudohalogen replacement of the azido group by treatment with nucleophilic reagents, such as ammonia and various amines. [citation needed]This compound is used as a reagent for the synthesis of peptides by virtue of its reactions with carboxylic acids leading to either the urethane or the amide.
