Triethylsilane Chemical Properties,Uses,Production
Description
Triethylsilane is a useful versatile reductant since it has a active hydride. It can be used for mediated the palladium-catalyzed dehalogenation reaction of alkyl or aryl halides, the reduction of primary, secondary, and tertiary chlorides, bromides, and iodides catalyzed by iridium, as well as efficient reduction of multiple bonds, azides, imines, and nitro groups, as well as benzyl group and allyl group deprotection. It is also specifically for the hydrosilation of olefins to give alkyl silanes. It is also the catalyst for synthesis of a spiro-oxindole blocker of Nav1.7 for the treatment of pain, redox initiated cationic polymerization and Beckmann rearrangement of cyclododecanone oxime as well as regioselective reductive coupling of enones and allenes.
Chemical Properties
Clear liquid
Uses
Triethylsilane is a trialkylsilicon hydride used in the synthesis of alkylsilanes via hydrosilation of olefins. 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.
Definition
ChEBI: Triethylsilane is an organosilicon compound. It has a role as a reducing agent.
Application
Triethylsilane is used as a reducing agent inmany organic synthetic reactions.
Used to reduce metal salts. Enhances deprotection of t-butoxycarbonyl-protected amines and tert-butylesters.
Used in the reductive amidation of oxazolidinones with amino acids to provide dipeptides.
Converts aldehydes to symmetrical and unsymmetrical ethers.
Used in the "in-situ" preparation of diborane and haloboranes.
Fire Hazard
Highly flammable; flash point －4°C (25°F)
(Aldrich 1996).
It does not ignite spontaneously in air,
but it can explode on heating. The ease
of oxidation of this compound is relatively
lower than mono- and dialkylsilanes. Reaction
with oxidizing substances, however,
can be violent. Reaction with boron trichloride
could be explosive at room temperature.
Even at 78°C ( 108°F), mixing these
reagents caused pressure buildup and combustion
(Matteson 1990).
Purification Methods
Reflux triethylsilane over molecular sieves, then distil it. It is passed through neutral alumina before use [Randolph & Wrighton J Am Chem Soc 108 3366 1986]. [Beilstein 4 IV 3895.]
