Carbosilanes

Tetramethylsilane (abbreviated as TMS) is the organosilicon compound with the formula Si(CH3)4. It is a colorless liquid. It is the simplest tetraorganosilane. Like all silanes, the TMS framework is tetrahedral. TMS is a building block in organometallic chemistry but also finds use in diverse niche applications.

Hexamethyldisilane (TMS2) is the organosilicon compound with the formula Si2(CH3)6, abbreviated Si2Me6. It is a colourless liquid, soluble in organic solvents. ==Synthesis and reactions== Hexamethyldisilane can be produced by Wurtz-like coupling of trimethylsilyl chloride in the presence of a reducing agent such as potassium graphite: With an excess of the reductant, the alkali metal silyl derivative is produced:

Trimethylsilane is the organosilicon compound with the formula (CH3)3SiH. It is a colorless gas. It is a trialkylsilane. The Si-H bond is reactive. Being a gas, it is less commonly used as a reagent than the related triethylsilane, which is a liquid at room temperature.

Phenylsilane, also known as silylbenzene, a colorless liquid, is one of the simplest organosilanes with the formula C6H5SiH3. It is structurally related to toluene, with a silyl group replacing the methyl group. Both of these compounds have similar densities and boiling points due to these similarities. Phenylsilane is soluble in organic solvents.

Trimethylsilyldiazomethane is the organosilicon compound with the formula (CH3)3SiCHN2. It is classified as a diazo compound. Trimethylsilyldiazomethane is commercially available as solutions in hexanes, DCM, and ether. It is a specialized reagent used in organic chemistry as a methylating agent for carboxylic acids. It is a safer replacement for diazomethane, which is a sensitive explosive gas, whereas trimethylsilyldiazomethane is a relatively stable liquid and thus easier to handle.

Methylsilane is the organosilicon compound with the formula . It is a colorless gas that ignites in air. It can be prepared by reduction of methyltrichlorosilane with lithium aluminium hydride. It has been investigated as a precursor to silicon carbide.

Trimethylsilylacetylene is the organosilicon compound with the formula . A colorless liquid, "tms acetylene", as it is also called, is used as a source of Acetylide| anion in organic synthesis.

Trifluoromethyltrimethylsilane (known as Ruppert-Prakash reagent, TMSCF3) is an organosilicon compound with the formula CF3Si(CH3)3. It is a colorless liquid. The compound is a reagent used in organic chemistry for the introduction of the trifluoromethyl group.

Vinylsilane refers to an organosilicon compound with chemical formula CH2=CHSiH3. It is a derivative of silane (SiH4). The compound, which is a colorless gas, is mainly of theoretical interest.

Triethylsilane , also known as TES or triethylsilicon hydride, is the organosilicon compound with the formula (C2H5)3SiH. It is a trialkylsilane. The Si-H bond is reactive.

Dimethylsilane is a compound with the formula C2H8Si. It is a flammable colorless gas. It is used in chemical vapor deposition.
