Trapping Experiments on a Trichlorosilanide Anion: a Key Intermediate of Halogenosilane Chemistry

Trapping Experiments on a Trichlorosilanide Anion: a Key Intermediate of Halogenosilane Chemistry

Trapping experiments were carried out on the [SiCl3]− anion, which has been postulated as a key intermediate in various reactions of HSiCl3 and Si2Cl6. While BCl3 failed as a trapping reagent, the use of BI3 allowed isolation of an [I3BSiI3]− adduct, which provides valuable experimental evidence for the existence of [SiX3]− ions in the solution phase. The molecular and electronic structure of the adduct has been characterized by X-ray crystallography and quantum-chemical calculations.
