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
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.
