Applications · 4 items

UsesTris(trimethylsilyl)silane is used in hydrosilylations of carbonyls, radical reactions, reductions of acid chlorides, and carbon-halogen bonds. It acts a mediator of radical reactions and considered to be a nontoxic substitute for tri-n-butylstannane in radical reactions. It forms complexes with transition metals and main group elements. Further, it is utilized in carbon-carbon bond forming reactions.

UsesTris(trimethylsilyl)silane) is used in the synthesis of silated alkenes and alkynes. Also used in the preparation of fused quinolines.

UsesReducing and hydrosilyating agent.

General DescriptionTris(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.
