Tris(trimethylsilyl)silane, 97%, Thermo Scientific Chemicals

Product Code. 11420627

Brand: Thermo Scientific Alfa Aesar B22457.14

Description

Tris(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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand.
