“…No formation of trichlorogermane was observed. In some reports, ,, trichlorogermane, not tetrachlorogermane, has been reported as a main product for the reaction of germanium and hydrogen chloride. Thus, under our reaction conditions, the germanium−hydrogen bond in trichlorogermane was completely converted to the germanium−chlorine bond by an attack of hydrogen chloride.…”

“…The reactions of germanium with various alkyl and aryl halides have also been reported for the direct synthesis of alkylhalogermanes and arylhalogermanes, respectively. [2][3][4][5] Only organic halides are reactive to directly synthesize organogermanes. In refs 2-5 copper and silver have been used as the catalysts, and these metals have formed the germanium-metal intermetallic compounds, in which germanium atom reacts with organic halides.…”

“…Elemental germanium reacts with methyl chloride with use of a copper catalyst to form methylchlorogermanes. , This is called “direct synthesis” since organogermanes are synthesized directly from elemental germanium. The reactions of germanium with various alkyl and aryl halides have also been reported for the direct synthesis of alkylhalogermanes and arylhalogermanes, respectively. − Only organic halides are reactive to directly synthesize organogermanes. In refs −5 copper and silver have been used as the catalysts, and these metals have formed the germanium−metal intermetallic compounds, in which germanium atom reacts with organic halides.…”

Direct Synthesis of Organotrichlorogermanes by the Reaction of Elemental Germanium, Hydrogen Chloride, and Alkene

The reaction of elemental germanium, hydrogen chloride, and ethylene with copper(I) chloride catalyst gave ethyltrichlorogermane with a 66% selectivity, tetrachlorogermane also being formed. The addition of tetrachlorogermane to the reaction system increased the formation rate of ethyltrichlorogermane. The reaction of germanium, tetrachlorogermane, and butadiene resulted in the formation of 1,1-dichlorogermacyclopent-3-ene. These results indicate the intermediacy of dichlorogermylene, which is formed by the reaction of elemental germanium with tetrachlorogermane. In place of ethylene, allyl chloride was fed with hydrogen chloride. Allyltrichlorogermane was obtained with a 92% selectivity together with a small amount of tetrachlorogermane. It is highly plausible that the formation of allyltrichlorogermane is caused by the insertion of dichlorogermylene intermediate to the carbon-chlorine bond of allyl chloride.

Phenyltrichlorogermane Synthesis by the Reaction of Chlorobenzene and the Dichlorogermylene Intermediate Formed from Elemental Germanium and Tetrachlorogermane

2001

View full text Add to dashboard Cite

Phenyltrichlorogermane was synthesized with high selectivity, 96%, from elemental germanium, tetrachlorogermane, and chlorobenzene using no catalyst, almost all germanium and tetrachlorogermane being converted. Dichlorogermylene was formed as a reaction intermediate by the reaction of germanium with tetrachlorogermane and inserted into the C-Cl bond of chlorobenzene to yield phenyltrichlorogermane.
