General Description

Hexaphenyldigermane is a chemical compound with the formula (C6H5)3Ge-Ge(C6H5)3. It is a colorless, crystalline solid at room temperature and is highly reactive due to the presence of the germanium-germanium bond. Hexaphenyldigermane is commonly used as a precursor for the synthesis of various organogermanium compounds and as a source of elemental germanium in chemical vapor deposition processes. It is also used in the manufacturing of semiconductors and as a reagent in organic synthesis. Due to its reactivity and potential toxicity, caution should be exercised when handling hexaphenyldigermane, and appropriate safety measures should be followed to prevent exposure.

A RE-EXAMINATION OF THE ELECTROCHEMICAL REDUCTION OF HALOSILANES AND HALOGERMANES

The electrochemical reduction peaks previously observed at about -0.4 V vs.SCE in the case of chloro- or bromo-silanes and -germanes actually refer to reduction of HCl or HBr formed by hydrolysis arising from traces of water in the solvent.This hydrolysis is catalysed by nucleophilic solvents.The electrochemical reduction of halo-silanes and -germanes in aprotic solvents giving the corresponding disilanes and digermanes is shown to be an irreversible process taking place at a low potential (-2 to -2.5 V vs.SCE).

Hydrogermolysis reactions involving the α-germylated nitriles R3GeCH2CN (R = Ph, Pri, But) and germanium amides R3GeNMe2 (R = Pri, But) with Ph3GeH: Substituent-dependent reactivity and crystal structures of Pri3GeGePh3 and But3Ge[NHC...

Title full: Hydrogermolysis reactions involving the α-germylated nitriles R3GeCH2CN (R = Ph, Pri, But) and germanium amides R3GeNMe2 (R = Pri, But) with Ph3GeH: Substituent-dependent reactivity and crystal structures of Pri3GeGePh3 and But3Ge[NHC(CH3)CHCN]. The α-germylated nitriles R3GeCH2CN (R = Ph, Pri, But) and germanium amides R3GeNMe2 (R = Pri and But) have been prepared and characterized and their reactivity with Ph3GeH in CH3CN has been explored to investigate their utility for the construction of Ge-Ge bonds. In each case the phenyl and iso-propyl derivatives furnish the corresponding digermanes R3GeGePh3 (R = Ph, Pri) where the amide reagents are converted to R3GeCH2CN in situ which subsequently react with Ph3GeH. The rate of the Ge-C bond cleavage reactions was found to depend on the steric and electronic properties of the organic substituents. Attempted synthesis of But3GeGePh3 by these methods did not result in the desired product but rather in isolation of the 3-amidocrotononitrile species But3Ge[NHC(CH3)CHCN]. The crystal structures of Pri3GeGePh3 and But3Ge[NHC(CH3)CHCN] have been determined.
