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 ...
It can be manufactured by the reaction of hot, concentrated lithium hydroxide with chlorine: 3 Cl 2 + 6 LiOH → 5 LiCl + LiClO 3 + 3 H 2 O. Lithium chlorate has one of the highest solubilities in water for a chemical compound. It is also a six-electron oxidant. Its electrochemical reduction is facilitated by acid, electrocatalysts and redox ...
Lithium chloride is a chemical compound with the formula Li Cl.The salt is a typical ionic compound (with certain covalent characteristics), although the small size of the Li + ion gives rise to properties not seen for other alkali metal chlorides, such as extraordinary solubility in polar solvents (83.05 g/100 mL of water at 20 °C) and its hygroscopic properties.
Water-reactive substances [1] are those that spontaneously undergo a chemical reaction with water, often noted as generating flammable gas. [2] Some are highly reducing in nature. [3] Notable examples include alkali metals, lithium through caesium, and alkaline earth metals, magnesium through barium.
Periodic Videos (also known as The Periodic Table of Videos) is a video project and YouTube channel on chemistry. It consists of a series of videos about chemical elements and the periodic table , with additional videos on other topics in chemistry and related fields.
Lithium hypochlorite is a chemical compound with the chemical formula of Li O Cl. It is the lithium salt of hypochlorous acid. It consists of lithium cations (Li +) and hypochlorite anions (− OCl). It is a colorless, crystalline compound. It has been used as a disinfectant for pools, and is also used as a reagent for some chemical reactions.
Lithium nitride is prepared by direct reaction of elemental lithium with nitrogen gas: [2] 6 Li + N 2 → 2 Li 3 N. Instead of burning lithium metal in an atmosphere of nitrogen, a solution of lithium in liquid sodium metal can be treated with N 2. Lithium nitride must be protected from moisture as it reacts violently with water to produce ammonia:
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
