应用

Tris(triethylsilyl)silane can be incorporated as a directing group for various regio- and stereo-selective reactions. Hydrogen abstraction from tris(triethylsilyl)silane yields highly stable silyl radical.

Tris(triethylsilyl)silane can be used as a hydrogen atom donor reagent in chemical synthesis due to its weak Si-H bond. Hydrogen abstraction from tris(triethylsilyl)silane yields a highly stable silyl radical.
It can be used as a reagent:

In the radical coupling reaction to generate C-C bonds from alkyl-halogen compounds using iridium and nickel catalysts.
To synthesize α-arylated product via cross-electrophile coupling reaction between α-chloro carbonyl and aryl bromide in the presence of nickel and iridium catalysts.
