Dimethyldichlorosilane is a tetrahedral organosilicon compound with the formula Si(CH 3) 2 Cl 2. At room temperature it is a colorless liquid that readily reacts with water to form both linear and cyclic Si-O chains. Dimethyldichlorosilane is made on an industrial scale as the principal precursor to dimethylsilicone and polysilane compounds.
It is a yellow solid that is soluble in some organic solvents. It is used for palladium-catalyzed coupling reactions, e.g. the Sonogashira–Hagihara reaction. The complex is square planar. Many analogous complexes are known with different phosphine ligands.
Dichlorosilane, or DCS as it is commonly known, is a chemical compound with the formula H 2 SiCl 2. In its major use, it is mixed with ammonia (NH 3) in LPCVD chambers to grow silicon nitride in semiconductor processing. A higher concentration of DCS·NH 3 (i.e. 16:1), usually results in lower stress nitride films.
Bis(triphenylphosphine)platinum chloride is a metal phosphine complex with the formula PtCl 2 [P(C 6 H 5) 3] 2. Cis- and trans isomers are known. Cis- and trans isomers are known. The cis isomer is a white crystalline powder, while the trans isomer is yellow. [ 3 ]
MeSiCl 3 + 3 H 2 O → MeSi(OH) 3 + 3 HCl. The silanol is unstable and will eventually condense to give a polymer network: MeSi(OH) 3 → MeSiO 1.5 + 1.5 H 2 O. Methyltrichlorosilane undergoes alcoholysis (reaction with alcohol) to give alkoxysilanes. Methanol converts it to trimethoxymethylsilane: MeSiCl 3 + 3 CH 3 OH → MeSi(OCH 3) 3 + 3 HCl
The Rh-P, Rh-C, and Rh-H distances are 2.32, 1.83, and 1.60 Å, respectively. [ 3 ] [ 4 ] This complex is one of a small number of stable pentacoordinate rhodium hydrides. Use in hydroformylation
The vapor pressure function according to Antoine is obtained as log 10 (P/1 bar) = A − B/(T + C) (P in bar, T in K) with A = 5.44591, B = 1767.766 K and C = −44.888 K in a temperature range from 291 K to 358 K. [2] Below the melting point at −4.5 °C, [12] The 1 H NMR in CDCl 3 shows a singlet at δ=0.14 ppm.
This group consists of three methyl groups bonded to a silicon atom [−Si(CH 3) 3], which is in turn bonded to the rest of a molecule. This structural group is characterized by chemical inertness and a large molecular volume , which makes it useful in a number of applications.
