Unsymmetrically substituted tri- and tetraalkoxysilanes were surprisingly found to be configurationally stable and easy to prepare. It was found that compounds of type MeSi(OR)2(OR′), MeSi- (OR)(OR′)(OR″), Si(OR)2(OR′)2, Si(OR)2(OR′)(OR″), Si(OR)3(OR′), and even Si(OR)(OR′)(OR″)(OR*) could be obtained by sequential addition of a variety of chiral and achiral alcohols to methyltrichlorosilane or tetrachlorosilane in the presence of pyridine. In the case of MeSi(OR)(OR′)(OR″) and Si(OR)(OR′)(OR″)(OR*), two types of compounds that have never been prepared before, were obtained in good yield.
