Abstract
Alkoxy (isocyanato) silanes were synthesized by the reaction of tri- o r tetraisacyanatosilane with ethanol, isopropyl alcohol, or t-butyl al cohol. Due to the milder reactivity of the isocyanatosilanes compared with that of the corresponding chlorosilanes, the substitution reactio n was easily controlled by proper molar ratio and use of bulky alcohol with an appropriate catalyst. As a result, alkoxy(isocyanato) silanes were prepared and isolated by distillation in high yields.
