Abstract
Treatment of substituted arylbromides with tert-butyllithium in diethyl ether at -78˚C, followed by the addition to dichlorodiethoxysilane, leads to the quantitative formation of diaryldiethoxysilanes. Diaryldiethoxysilanes can be reduced to the corresponding diarylsilanes by stirring with lithium aluminum hydride in diethyl ether. This method avoids the handling of gaseous and explosive dichlorosilane.
