Application
Tetramethylsilane can be used as:
- A precursor to synthesize α-SiC by chemical vapor deposition.
- A reactant to synthesize 1,3,5,7-tetramethyladamantane from adamantane in the presence of aluminum chloride and dichloromethane.
- A solvent for the hydroaminomethylation of 1-octene with morpholine.
- A methylating reagent for the conversion of germanium tetrachloride to tetramethylgermanium, trimethylgermanium chloride, dimethylgermanium dichloride or methylgermanium trichloride.
