Triethylgermanium hydride
Triethylgermanium hydride (CAS: 1188-14-3), with the linear formula (C2H5)3GeH and a molecular weight of 160.83 g/mol, is a liquid organogermanium compound. It serves as a valuable reagent in chemical synthesis, particularly in hydrogermylation reactions. This precursor is also utilized in materials science and micro/nanoelectronics as a CVD and ALD precursor for depositing germanium-containing thin films.
Hydrogermylation Reagent
Triethylgermanium hydride readily undergoes hydrogermylation reactions with unsaturated compounds such as alkyl propiolates. This process yields substituted triethylgermylacrylates, which are useful intermediates in organic synthesis.
CVD and ALD Precursor
As a vapour deposition precursor, triethylgermanium hydride can be employed in Chemical Vapour Deposition (CVD) and Atomic Layer Deposition (ALD) processes. It enables the deposition of germanium-containing thin films for microelectronics and materials science applications.
Organogermanium Synthesis
This compound is a foundational building block for the synthesis of more complex organogermanium compounds. Its hydride functionality allows for diverse synthetic transformations.
