Lithium imide is an inorganic compound with the chemical formula Li 2 N H. This white solid can be formed by a reaction between lithium amide and lithium hydride. [1] LiNH 2 + LiH → Li 2 NH + H 2. The product is light-sensitive and can undergo disproportionation to lithium amide and characteristically red lithium nitride. 2 Li 2 NH → LiNH 2 ...
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]
In organometallic chemistry, organolithium reagents are chemical compounds that contain carbon–lithium (C–Li) bonds.These reagents are important in organic synthesis, and are frequently used to transfer the organic group or the lithium atom to the substrates in synthetic steps, through nucleophilic addition or simple deprotonation.

An intramolecular S N 2 reaction by the anion forms the cyclic backbone of morphine. [14] Synthesis of morphine using lithium–halogen exchange. 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.
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.
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.
Lithium is a highly reactive alkali metal that is widely used in various industrial applications due to its unique properties. Lithium compounds are formed by combining lithium with other elements, such as oxygen, sulfur, and chlorine, to form different chemical compounds.
Lithium hydroxide absorbs carbon dioxide from the air by forming lithium carbonate, and is preferred over other alkaline hydroxides for its low weight. Lithium peroxide (Li 2 O 2) in presence of moisture not only reacts with carbon dioxide to form lithium carbonate, but also releases oxygen. [174] [175] The reaction is as follows:
