clear colorless to pale yellow liquid | [Uses]
Reducing and hydrosilyating agent. | [Uses]
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. | [Uses]
Tris(trimethylsilyl)silane) is used in the synthesis of silated alkenes and alkynes. Also used in the preparation of fused quinolines. | [Application]
Undergoes exothermic decomposition at >100 °C.
Radical-based reducing agent for organic halides,
selenides, xanthates and isocyanides and ketones in high
yields. Can provide complementary stereoselectivity to tri-n-butyltin hydride in the reduction of gem dihalides. Mild
reducing agent in nucleoside chemistry. | [General 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. | [Purification Methods]
Purify it by fractional distillation and taking the middle cut. Store it under N2 or Ar as it is PYROPHORIC and is an IRRITANT. [Chatgilialoglu et al. J Org Chem 53 3641 1988, Balestri et al.
