Beschreibung

Allgemeine Beschreibung

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.

Anwendung

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
