Abstract:

The addition of trialkoxysilanes to olefins was demonstrated by interacting triethoxysilane, triisopropoxysilane, tributoxysilane, trisec-butoxy-silane, and tritert-butoxysilane with 1-nonene and 1-decene in the presence of chloroplatinic acid and platinized charcoal. In the presence of chloroplatinic acid a yield of 30 to 40 was obtained. The addition of tritert-butoxysilane, due to steric hindrance, gave the lowest yields of all 12. Decyltributoxysilane and nonyltriisopropoxysilane were also obtained by direct synthesis, by the reaction of nonyltrichlorosilane and decyltrichlorosilane with the corresponding alcohols. The physicochemical properties of the alkyl-trialkoxysilanes obtained by both methods, addition to olefins and reaction with alcohols, were identical.
