General description
Trichlorosilane is used as a reducing agent in certain chemical reactions or as a starting material for the synthesis of various organosilicon compounds. Trichlorosilane is generally used for the asymmetric hydrosilylation of olefins in the presence of palladium catalysts coordinated with chiral monodentate phosphorus ligands to generate chiral organosilanes.
Application
Trichlorosilane has been used to synthesize 11-dicyclohexylphosphino-12-phenyl-9,10-dihydro-9,10-ethenoanthracene (H-KITPHOS) via reduction of 11-dicyclohexylphosphinoyl-12-phenyl-9,10-dihydro-9,10-ethenoanthracene.
Other possible applications:
L-valine-derived catalyst to form secondary amines.
derivatives is an effective reagent for the reduction of imines to form
enantiomerically enriched amines.
Other possible applications:
- Asymmetric reduction of N-aryl ketimines in the presence of a novel
L-valine-derived catalyst to form secondary amines.
- Hydrosilylation of imidazolinones to form chiral imidazolidinones in the presence of a 2,2′-bispyrrolidine based Lewis base organocatalyst.
- Trichlorosilane activated with chiral N-formylproline
derivatives is an effective reagent for the reduction of imines to form
enantiomerically enriched amines.
- Trichlorosilane reacts with dimethylformamide to form hypervalent hydridosilicates, which can reduce aldehydes to alcohols, imines to amines, and also for the reductive amination of aldehydes.

We report herein three unprecedented alkyltrichlorosilane surface modifiers bearing pentafluorophenyl ester (PFP), benzothiosulfonate (BTS), or novel β-propiolactone (BPL) functionalizable terminal groups. Evidence is provided that these molecules can be prepared in very high purity (as assessed by NMR) through a

As an analogue to the vapor-liquid-solid process, the solution-liquid-solid (SLS) method offers a mild solution-phase route to colloidal 1D nanostructures with controlled sizes, compositions, and properties. However, direct growth of 1D nanostructure arrays through SLS processes remains in its infancy.
