Triethylsilane is used for the hydrosilation of olefins to prepare alkyl silanes. It acts as a reducing agent in the reduction of 2-chromanols, since it has an active hydride. It acts as a catalyst for redox initiated cationic polymerization, regioselective reductive coupling of enones and allenes, and Beckmann rearrangement of cyclododecanone oxime. It is associated with trifluoroacetic acid and involved in the selective reduction of alkenes.
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.
Aplicaciones
El trietilsilano se utiliza para la hidrosilación de olefinas para preparar silanos alquilos. Actúa como agente reductor en la reducción de 2cromanoles, ya que tiene un hidruro activo. Actúa como catalizador para la polimerización catiónica iniciada por redox, el acoplamiento reductivo regioselectivo de enones y alenos, y la transposición de Beckmann de la oxima de ciclododecanona. Se asocia con el ácido trifluoroacético y participa en la reducción selectiva de alquenos.
Solubilidad
Miscible con agua.
Notas
Incompatible con ácidos fuertes, agua y bases.

- In combination with TFA, ionic hydrogenation of alkenes occurs. This can be a useful alternative to catalytic hydrogenation, since selective reduction, e.g. of the more branched double bond of a diene can be achieved. For a review of ionic hydrogenation, see: Synthesis, 633 (1974):
