Description

General description

Tris(trimethylsilyl)silane is an organosilicon generally used as a radical reducing agent for xanthates, organic halides, isocyanides, selenides, and acid chlorides. It is also used for hydrosilylation of alkenes, alkynes, and dialkyl ketones.

Application

Super Silyl Protecting Groups

Used in:

Hydrosilylations
Radical reactions
Reductions of acid chlorides
Reductions of carbon-halogen bonds
Hydrosilations of carbonyls

Another common application involves the use of the tris(trimethylsilyl)silyl (TTMSS, or super silyl) group when complexed with transition metals and main group elements

More recently, the super silyl group is being utilized in carbon–carbon bond forming reactions
