The substituent redistribution of hydrosilanes on silicon through C–Si and Si–H bond cleavage and reformation is of great interest and importance, but this transformation is usually difficult to achieve in a selective fashion. By using electron-rich aromatic hydrosilanes, we have achieved for the first time the selective C–Si/Si–H bond homo- and cross-metathesis of a series of hydrosilanes in the presence
通过C-Si和Si-H键的裂解和重整作用,氢硅烷在硅上的取代基重新分布引起人们极大的兴趣和重要性,但是这种转化通常很难以选择性的方式实现。通过使用富含电子的芳族氢硅烷,我们首次实现了在硼催化剂B(C 6 F 5)存在下一系列氢硅烷的选择性C-Si / Si-H键均位和交叉复分解。3。该方案具有简单的反应条件,高的化学选择性,宽的底物范围和高的功能耐受性,为合成多取代的功能性硅烷提供了一条新途径。
