The influence of reagents, solvent polarity, and temperature on the etherification of chlorosilanes ClCH2SiCl3, VinSiCl 3, PrSiCl3, and Ph3SiCl with ethanol was studied. Influence of reaction temperature on the ratio of the synthesized alkoxysilane and related side-product siloxane is revealed. Use of excess alcohol is shown to increase the content of siloxane. Introduction of FeCl 3 does not affect the synthesis. Solvents are shown to influence the reaction rate: the rate constant increases with increasing ε parameter of the solvent. The rate constant of etherification of chlorosilanes with ethanol falls in the series: ClCH2SiCl3 > VinSiCl3 > PrSiCl3. An explanation of the regularities is suggested.

Alkyl(aryl)trichloro- or dialkyl(diaryl)dichlorosilanes react with tetraalkoxysilanes Si(OMe)4, Si(OEt)4, and Si(OBu)4 to give partially etherfied alkyl(aryl)chlorosilanes RSiCl2(OAlk), RSiCl(OAlk)2, and R2SiCl(OAlk).
