Organosilicon compounds alkoxysilanes

Since the orbital interaction plays a major role, the oxidation potentials of a-het-eroatom-substituted organosilicon compounds depend on the geometry. As a matter of fact, the oxidation potentials of a-alkoxysilanes in which the rotation around the C-O bond is restricted vary dramatically with the torsion angle of Si-C-O-C (Table 4) [115]. 

The most commonly used organosilicon compounds are silicones as described above. The others are chlorosilanes, alkoxysilanes, silazanes, fluoroalkylsilanes and polysilanes as shown in Table 8.3 [31]. 

Alkoxysilanes SiH (OR)4 are important intermediates in organosilicon production. Triethoxysilane SiH(OC2H5)3, in particular, is used in compound and release agent manufacture, for semi-conducting silicon production, etc. 

Chlorosilanes are the most important functional silicon compounds. As described above, chlorosilanes can be used for silicon—carbon and silicon—silicon bond formation. In addition, chlorosilanes can be converted into other functional silicon compounds, such as hydrosilanes, alkoxysilanes, and aminosi-lanes. Hydrosilanes, alkoxysilanes, and aminosilanes can be transformed furthermore into other functional silicon compounds. Combination of functional group transformation and silicon-carbon and silicon—silicon bond formation of chlorosilanes are essential for the construction of organosilicon clusters.
