In organosilicon chemistry, silanes are a diverse class of charge-neutral organic compounds with the general formula SiR4. The R substituents can any combination of organic [1] or inorganic groups. [2] Most silanes contain Si-C bonds, and are discussed under organosilicon compounds. Some contain Si-H bonds and are discussed under hydrosilanes.
Triethoxysilane is an organosilicon compound with the formula HSi (OC 2 H 5) 3. It is a colourless liquid used in precious metal-catalysed hydrosilylation reactions. The resulting triethoxysilyl groups are often valued for attachment to silica surfaces. [1] Compared to most compounds with Si-H bonds, triethoxysilane exhibits relatively low ...

Tetraethyl orthosilicate, formally named tetraethoxysilane (TEOS), ethyl silicate is the organic chemical compound with the formula Si (OC 2 H 5) 4. TEOS is a colorless liquid. It degrades in water. TEOS is the ethyl ester of orthosilicic acid, Si (OH) 4. It is the most prevalent alkoxide of silicon.
Triethylsilane is the organosilicon compound with the formula (C 2 H 5) 3 SiH. It is a trialkylsilane. The Si-H bond is reactive. This colorless liquid is used in organic synthesis as a reducing agent and as a precursor to silyl ethers. [2] As one of the simplest trialkylsilanes that is a liquid at room temperature, triethylsilane is often used ...
