Lithium hydroxide is an inorganic compound with the formula LiOH. It can exist as anhydrous or hydrated, and both forms are white hygroscopic solids. They are soluble in water and slightly soluble in ethanol. Both are available commercially. While classified as a strong base, lithium hydroxide is the weakest known alkali metal hydroxide.
Lithium bromide (LiBr) is a chemical compound of lithium and bromine. Its extreme hygroscopic character makes LiBr useful as a desiccant in certain air conditioning systems. [ 9 ]

Lithium will ignite and burn in oxygen when exposed to water or water vapor. In moist air, lithium rapidly tarnishes to form a black coating of lithium hydroxide (LiOH and LiOH·H 2 O), lithium nitride (Li 3 N) and lithium carbonate (Li 2 CO 3, the result of a secondary reaction between LiOH and CO 2).

The salt theoretically results from the neutralization of hypofluorous acid (HOF) and lithium hydroxide (LiOH). It can be formed by the action of fluorine on lithium hydroxide: 6 F 2 + 6 LiOH → 2 LiF + O 2 + 4 LiOF + 6 HF
The filtrate consists of fairly pure methyllithium. Alternatively, commercial methyllithium can be treated with dioxane to precipitate LiBr(dioxane), which can be removed by filtration. [2] The use of halide-free vs LiBr-MeLi has a decisive effect on some syntheses. [3]
LiOH + H 2 O 2 → LiOOH + H 2 O. This lithium hydroperoxide may exist as lithium peroxide monoperoxohydrate trihydrate (Li 2 O 2 ·H 2 O 2 ·3H 2 O). Dehydration of this material gives the anhydrous peroxide salt: 2 LiOOH → Li 2 O 2 + H 2 O 2. Li 2 O 2 decomposes at about 450 °C to give lithium oxide: 2 Li 2 O 2 → 2 Li 2 O + O 2
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.
