Usage

General Description

Hexamethyldigermane is a chemical compound with the molecular formula Ge2H12. It is a clear, colorless liquid with a sharp, unpleasant odor. Hexamethyldigermane is primarily used as a precursor for the chemical vapor deposition of thin film germanium semiconductors. It is also used in the synthesis of organogermanium compounds, which have potential applications in the field of organic chemistry and material science. Hexamethyldigermane is highly flammable and reactive with strong oxidizing agents, and should be handled and stored with caution. It is important to follow strict safety protocols when working with this compound to prevent potential hazards.

On the Role of the Solid-Gas Interface in the Thermolysis of Trimethylgermane and Trimethylstannane

Metal film surfaces have a profound effect on the thermal decomposition of Me3MH (M = Ge and Sn), both of which unusually decompose by half-order kinetics at elevated temperature.

Photochemical Reactions of Vinyl-, Styryl- and Benzyl-Substituted Digermanes

Photochemical reactions of vinyl-, styryl- and benzyl-substituted digermanes by chemical trapping experiments.Photolysis of vinylpentamethyldigermane afforded 1-trimethyl-2-(pentamethyldigermyl)ethane as a major product, and styrylpentamethyldigermanes gave mainly styryltrimethylgermane.On the other hand, photolysis of benzyl-substituted digermanes (benzylpentamethyldigermane and 1,2-dibenzyltetramethyldigermane) gave hydrogermanes and hydrodigermanes as main products, respectively.These products were derived from germyl radicals generated by photoinduced homolysis of the germanium-germanium bond.In carbon tetra chloride (CCl4), these germyl radicals were converted to the corresponding chlorogermanes by abstraction of a chlorine atom.Germylene species were also to be evolved from such photolyses.
