Abstract
Abstract Trialkyl orthoformates in the presence of aluminium chloride represent quite useful reagents to generate silicon alkoxides from chlorosilanes. 3-Cyanopropyltrichlorosilane and 2-[(2-trichlorosily)ethyl]-pyridine give the triethoxy compounds 3-cyanopropyltriethoxysilane and 2-[(2-triethoxysilyl)ethyl]-pyridine respectively. Via this route, in methylchlorooligosilanes a partial or complete exchange of the chlorine substituents for alkoxy groups occurs depending on the starting molar ratio of silane:HC(OR)3 (R Me, Et). SiCl2Me groups react to SiClMe(OR) first before SiMe(OR)2 groups are formed. (Si)2 SiClMe units are not affected by HC(OR)3.
