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.Super Silyl Protecting GroupsUsed in:HydrosilylationsRadical reactionsReductions of acid chloridesReductions of carbon-halogen bondsHydrosilations of carbonylsAnother common application involves the use of the tris(trimethylsilyl)silyl (TTMSS, or super silyl) group when complexed with transition metals and main group elementsMore recently, the super silyl group is being utilized in carboncarbon bond forming reactions
