Gallium trichloride is a common starting reagent for the formation of organogallium compounds, such as in carbogallation reactions. [44] Gallium trichloride reacts with lithium cyclopentadienide in diethyl ether to form the trigonal planar gallium cyclopentadienyl complex GaCp 3. Gallium(I) forms complexes with arene ligands such as ...
Gallium trichloride is a common starting reagent for the formation of organogallium compounds, such as in carbogallation reactions. [15] Gallium trichloride reacts with lithium cyclopentadienide in diethyl ether to form the trigonal planar gallium cyclopentadienyl complex GaCp 3. Gallium(I) forms complexes with arene ligands such as ...
Organogallium compounds can be synthesized by transmetallation, for example the reaction of gallium metal with dimethylmercury: 2Ga + 3Me 2 Hg → 2Me 3 Ga + 3 Hg. or via organolithium compounds or Grignards: GaCl 3 + 3MeMgBr → Me 3 Ga + 3MgBrCl. The electron-deficient nature of gallium can be removed by complex formation, for example
Gallium(I) oxide is a brown-black diamagnetic solid which is resistant to further oxidation in dry air. It starts decomposing upon heating at temperatures above 500 °C, and the decomposition rate depends on the atmosphere (vacuum, inert gas, air).
The Pentagon holds a strategic stockpile for germanium but currently has no inventory reserves for gallium, a spokesperson said on Thursday, after China announced export restrictions on the two ...
The spot price of gallium metal reached 1,975 yuan ($269.95) per kg on Oct. 18, up 18% since the start of July and up 8% since Aug. 1, d Chinese gallium prices hit 7-month high as demand improves ...
China is the biggest global source of gallium and germanium, which are produced in small amounts but are needed to make computer chips for mobile phones, cars and other products, as well as solar ...
Gallium is very different from indium in that it is only known to form 6 coordinate complexes with the fluoride ion. This can be rationalised by the smaller size of gallium (ionic radii of Ga(III) 62 pm, In(III) 80 pm). Salts containing the Ga 2 Cl 6 2− anion, where gallium has an oxidation state of +2, are known.
