triethylsilane

Triethylsilane , also known as TES or triethylsilicon hydride, is the organosilicon compound with the formula (C2H5)3SiH. It is a trialkylsilane. The Si-H bond is reactive.

It was first discovered by Albert Ladenburg in 1872 among the products of reduction of tetraethyl orthosilicate with sodium and diethylzinc. He also prepared it by a stepwise reduction via ethoxytriethylsilane and named it silicoheptyl hydride, reflecting the idea of a silicon compound analogous to a seven-carbon hydrocarbon. This colorless liquid finds occasion use in organic synthesis. As one of the simplest trialkylsilanes that is a liquid at room temperature, triethylsilane is often used in studies of hydrosilylation catalysis.
