General Description

HEXAETHYLDIGERMOXANE, also known as hexaethyl tetragermane, is a silicon-containing compound with the molecular formula Ge4(C2H5)6. It is a colorless liquid with a faint, garlic-like odor, and it is highly flammable. HEXAETHYLDIGERMOXANE is primarily used as a precursor in the synthesis of inorganic-organic hybrid materials and semiconductor nanoparticles, as well as in the production of thin-film transistors. It is also under investigation for its potential applications in electronic and optoelectronic devices. However, its toxicity and potential environmental impact have raised concerns, and careful handling and disposal practices are necessary when working with this chemical.

Reaction of organoelement hydrides R3EH (E = Si, Ge) with metal tert-butylate (M = Al, Ti)-tert-butyl hydroperoxide oxidative systems

Trialkyl(aryl)silanes and -germanes effectively react with metal (Al, Ti) tert-butylate-tert-butyl-hydroperoxide under mild conditions (room temperature, benzene or tetrachloromethane) mainly by the element-hydrogen bond. The character of the products depends on the nature of the element, the structure of the radical bound to it, and the solvent. The process is radical in nature. It includes the stages of formation of element-centered radicals and their reaction with the oxygen generated by the system. The intermediate organometallic peroxides can also acts as oxidants for the element (Si, Ge)-hydrogen bonds. 2005 Pleiades Publishing, Inc.

Etude comparative des reactions par transfert monoelectronique entre les germylamines primaires, secondaires et tertiaires et la 3,5-di-tert-butylorthoquinone

Several germylamines were treated with 3,5-di-t-butylorthoquinone (1).Competitive 1,2 and 1,4 additions resulted using the tertiary amine Et3GeNPh2.The thermally unstable 1,4 adduct gives 2,2-dialkyl-4,5-(6,8-di-t-butyl)benzo-2-germa-1,3-dioxolanne.The 1,2 adduct leads via intermolecular redistribution to bis(triethylgermyl)oxide ((Et3Ge)2O), and aminal with partial regeneration of the initial quinone.These reations seem to proceed solely via a mono-electron transfer mechanism; the aminyl radical Ph2N and the transitory o-semiquinonic germylated radical formed in the reaction have been characterized by ESR spectroscopy.The o-semiquinonic radical then gives O-germyl-3,5-di-t-butylcatechol by hydrogen abstraction.As ethylene and isobutene have been characterized, these hydrogen abstractions occur from ethyl groups linked to germanium and from t-butyl groups belonging to the organic moieties.In the reaction of the secondary amine Et3GeN(H)Ph, a germylaminyl radical is mainly formed instead of an o-semiquinonic germylated radical, which can explain the lesser amount of germadioxolanne obtained.The quinone 1 is partially transformed in o-diphenol under the action of Mes3GeNH2.No germylated adducts are observed.Aminyl radicals characterized in several reactions between germylamines and 1 were also obtained via monoelectronic transfer between lithium amids and tri-t-butylnitrozobenzene (BNB), thus providing a new, useful method for obtaining such species.
