Added importance centers on the dialkyldialkoxysilanes in view of the fact that they are satisfactory intermediates for the manufacture of silicon resins. These compounds may be made by a modification of the Grignard method without the use of ether as a solvent,58 and many of the alkyltriethoxysilanes listed in the compound index at the end of this chapter also were made this way.69 The allyltri-ethoxysilane so prepared apparently did not polymerize, but the phenylethynylsilanes prepared by the following reactions... 

Salts of Grignard and analogous compounds are placed under the formula of the hydroxide. Organic silicon compounds are treated in the same manner when only one acid group is present. If more than one acid group is present, the salt is indexed under its own formula.

In general, the alkylalkoxysilanes behave like the alkylchloro-silanes in that they hydrolyze to form the various silicols or their dehydration products. It is not necessary to go through the separate classes of compounds, for their reactions and derivatives may be inferred from the known properties of the halides and the previously discussed properties of the silicon esters. Some of the representative compounds are listed in the index which follows this chapter,66 and a list of alkyltrialkoxysilanes is given in Krause and von Grosse.67... 

The communications revolution also relies on a diverse set of CVD technologies. Some components are similar to those used in silicon microelectronics, but many are unique, involving complex epitaxial heterostructures of SiGe or compound semiconductor (e.g., AlGaAs) alloys that are required to yield high frequency (1-100 GHz) device operation. The communication revolution also relies on optoelectronic components, such as solid state diode lasers (another complex heterostructure device), and these devices are often grown by CVD. - Even the fiberoptic cables that transmit the optical component of the communications network are manufactured using a CVD technique to achieve the desired refractive index profile. ... 

A further method for the synthesis of the title compounds with only hydrogen as byproduct is the base-catalyzed dehydrogenative coupling (index D) of ammonia and tris(hydridosilylethyl)boranes, B[C2H4Si(R)H2]3 (R = H, CH3). Initially, the strong base, e.g. n-butyl lithium, deprotonates ammonia. The highly nucleophilic amide replaces a silicon-bonded hydride to form a silylamine and lithium hydride, which then deprotonates ammonia, resuming the catalytic cycle. Under the conditions used, silylamines are not stable and by elimination of ammonia, polysilazane frameworks form. In addition, compounds B[C2l-L Si(R)H2]3 can be obtained from vinylsilanes, H2C=CHSi(R)H2 (R - H, CH3), and borane dimethylsulfide.
