A kinetic study has been made of the reaction of some 1-organosilatranes with aqueous-methanolic hydrochloric acid. The reaction is of first-order in both silatrane and acid, and for XC6H4,-silatranes electron release by X assists the reaction. For acid catalysis in water or in water/dioxan, the rate is effectively the same irrespective of whether protium oxide or deuterium oxide is used. It is suggested
动力学研究了一些1-有机基硅烷基酯与含水甲醇盐酸的反应。该反应在甲硅烷基和酸中都是一阶的,并且对于XC 6 H 4,通过X释放的-硅烷基转移电子有助于该反应。对于在水中或在水/二恶烷中的酸催化,无论使用氧化pro还是氧化氘,该速率均有效地相同。建议确定速率的步骤涉及氮原子的质子化与SiN键的断裂协同作用,质子化在过渡态几乎完成。
