Lithium imide is strongly basic and deprotonates even some extremely weak acids such as methane and ammonia, due to the very localized negative charge on the nitrogen, which carries two formal charges. It has uses in organic and organometallic chemistry. It has been investigated as a material for hydrogen storage. [1]
The inorganic imide is an inorganic chemical compound containing an anion with the chemical formula HN 2−, in which nitrogen atom is covalently bonded to one hydrogen atom (as in lithium imide Li 2 NH and calcium imide CaNH). The other name of that anion is monohydrogen nitride.
Under hydrogen at around 200°C, Li 3 N will react to form lithium amide. [10] Li 3 N + 2 H 2 → 2LiH + LiNH 2. At higher temperatures it will react further to form ammonia and lithium hydride. LiNH 2 + H 2 → LiH + NH 3. Lithium imide can also be formed under certain conditions. Some research has explored this as a possible industrial ...
A general linear imide functional group. In organic chemistry, an imide is a functional group consisting of two acyl groups bound to nitrogen. [1] The compounds are structurally related to acid anhydrides, although imides are more resistant to hydrolysis.
Lithium amide or lithium azanide is an inorganic compound with the chemical formula LiNH 2. It is a white solid with a tetragonal crystal structure. [1] Lithium amide can be made by treating lithium metal with liquid ammonia: [2] 2 Li + 2 NH 3 → 2 LiNH 2 + H 2. Lithium amide decomposes into ammonia and lithium imide upon heating. [3]
Lithium–halogen exchange is a crucial part of Parham cyclization. [15] In this reaction, an aryl halide (usually iodide or bromide) exchanges with organolithium to form a lithiated arene species. If the arene bears a side chain with an electrophillic moiety, the carbanion attached to the lithium will perform intramolecular nucleophilic attack ...
Hydrazoic acid, also known as hydrogen azide, azic acid or azoimide, [2] is a compound with the chemical formula HN 3. [3] It is a colorless, volatile, and explosive liquid at room temperature and pressure. It is a compound of nitrogen and hydrogen, and is therefore a pnictogen hydride. It was first isolated in 1890 by Theodor Curtius. [4]
In some terminal imido complexes, the M=N−C angle is 180° but often the angle is decidedly bent. Complexes of the type M=NH are assumed to be intermediates in nitrogen fixation by synthetic catalysts. [3] Typical Schrock-style olefin metathesis catalyst features imides as spectator ligands.
