A convenient procedure has been developed for the preparation of Group14 compounds by integrated palladium‐catalyzed cross‐coupling of aromatic iodides with the corresponding Group14hydrides in the presence of a base. The reaction conditions can be applied to the cross‐coupling of tertiary, secondary, and primary Group14 compounds. In most cases, the desired arylated products were obtained in synthetically
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。
