发现芳基硅烷、烯基硅烷、烯丙基硅烷和烷基硅烷在超临界水中经历极其容易和快速的C-Si键断裂。快速的C-Si键断裂甚至发生在坚固的未活化的四烷基硅烷上。对照实验揭示了超临界和亚临界条件之间以及超临界水和超临界甲醇之间的巨大差异，证明了超临界水在C-Si键断裂中的独特反应性。
Arylsilanes, alkenylsilanes, allylic silanes, and alkylsilanes were found to undergo extremely facile and rapid C−Si bond cleavage in supercritical water. The rapid C−Si bond cleavage occurred even with robust unactivated tetraalkylsilanes. The control experiments revealed the dramatic difference between supercritical and subcritical conditions and that between supercritical water and supercritical methanol, attesting to a unique reactivity of supercritical water in C−Si bond cleavage.
