Lithium enolates are formed through deprotonation of a C−H bond α to the carbonyl group by an organolithium species. Lithium enolates are widely used as nucleophiles in carbon–carbon bond formation reactions such as aldol condensation and alkylation. They are also an important intermediate in the formation of silyl enol ether.
Lithiophilite is a mineral containing the element lithium. It is lithium manganese(II) phosphate with chemical formula LiMnPO 4. It occurs in pegmatites often associated with triphylite, the iron end member in a solid solution series. The mineral with intermediate composition is known as sicklerite and has the chemical formula Li(Mn,Fe)PO 4).
Certain lithium compounds, also known as lithium salts, are used as psychiatric medication, [5] primarily for bipolar disorder and for major depressive disorder. [5]

Lepidolite is associated with other lithium-bearing minerals like spodumene in pegmatite bodies. It is the major source of the alkali metal rubidium. [13] In 1861, Robert Bunsen and Gustav Kirchhoff extracted 150 kg (330 lb) of lepidolite to yield a few grams of rubidium salts for analysis, and therefore discovered the new element rubidium.
Russian enrichment capacities focus on lithium-7 production by electrolysis of an aqueous lithium chloride solution using a mercury cathode, which is thus different from the COLEX process. [ 9 ] Although US nuclear industry relies heavily on Chinese and Russian enriched lithium, ecological concerns over the process may impede its future ...
Lithium is widely distributed in the lithosphere and mantle as a trace element in silicate minerals. [1] Lithium concentrations are highest in the upper continental and oceanic crusts. Chemical weathering at Earth’s surface dissolves lithium in primary minerals and releases it to rivers and ground waters.
3 is a lithium rich layered rocksalt structure that is made of alternating layers of lithium ions and lithium and manganese ions in a 1:2 ratio, similar to the layered structure of LiCoO 2. In the nomenclature of layered compounds it can be written Li(Li 0.33 Mn 0.67)O 2. [7] Although Li 2 MnO
