extremely facile and rapid C-Si bondcleavage in supercritical water. Rapid C-Si bondcleavage occurred even with robust unactivated tetraalkylsilanes. The control experiments revealed the dramatic difference between the 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
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发生极其容易和快速的 C-Si 键断裂。即使使用稳定的未活化四烷基硅烷,也会发生快速的 C-Si 键断裂。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 键断裂中具有独特的反应性。还发现酸,例如 HCl、HBr 和 H 2 SO 4 ,会促进超临界水中的 C-Si 键断裂。
