General Description

HEXAPHENYLDIGERMOXANE, also known as hexaphenyldigermoxane, is a chemical compound with the molecular formula (C6H5)3Ge-Ge(C6H5)3. It is a crystalline solid that is insoluble in water and has a high melting point. Hexaphenyldigermoxane is used in organogermanium chemistry as a precursor for the synthesis of other organogermanium compounds. It is also being explored for potential applications in materials science, such as in the development of new types of polymers and semiconductors. Additionally, research has been conducted to investigate its potential use in medicinal chemistry for the development of new pharmaceuticals and drugs. However, due to its toxic and potentially hazardous nature, proper precautions must be taken when handling and working with hexaphenyldigermoxane.

Reactions of titanium alcoholates Ti(OR)4 (R = n-Bu, t-Bu) with tertiary organic and organometallic hydroperoxides

tert-Butyl and cumyl hydroperoxides in the reactions with Ti(OR) 4 are reduced to alcohols with the evolution of oxygen via formation of titanium-containing peroxides and trioxides. The pathways of the reactions of Ti(OR)4 with triphenylelement hydroperoxides R3EOOH (E = C, Si, Ge) depend on element E and on the structure of R; the reactions involve the rearrangement of the peroxides, and with (n-BuO)4Ti the alkoxy group is oxidized either with preservation or with breakdown of the hydrocarbon skeleton.

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.
