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.
The Si–O bond distance is typically about 1.65 Å. [3] In the solid state, silanols engage in hydrogen-bonding. [4] Most silanols have only one OH group, e.g. trimethylsilanol. Also known are some silanediols, e.g., diphenylsilanediol. For sterically bulky substituents, even silanetriols have been prepared. [5] [3]
Silanes with one, two, three, or four Si-H bonds are called hydrosilanes. Silane is again the parent member. Examples: triethylsilane (HSi(C 2 H 5) 3) and triethoxysilane (HSi(OC 2 H 5) 3). Polysilanes are organosilicon compounds with the formula (R 2 Si) n. They feature Si-Si bonds. Attracting more interest are the organic derivatives such as ...
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
Stock and Somieski completed the hydrolysis of dichlorosilane by putting the solution of H 2 SiCl 2 in benzene in brief contact with a large excess of water. [3] [5] A large-scale hydrolysis was done in a mixed ether/alkane solvent system at 0 °C, which gave a mixture of volatile and nonvolatile [H 2 SiO] n.
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.
