Description

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. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
