A palladium-catalyzed three-component tandem reaction for stereoselective assembly of various tri- or tetrasubstituted vinylsilanes is established. This method enables the construction of two C–Si bonds and two C–C bonds by the disilylation of ortho-vinyl bromobenzenes generated in situ from 1-bromo-2-iodobenzenes and N-tosylhydrazones. More importantly, the substrate scope of this protocol was further demonstrated by the transformation of ortho-vinyl bromobenzenes generated from a range of aryl iodides and N-tosylhydrazone to vinylsilanes.

Pd通过三组分串联反应催化一锅法合成乙烯基硅烷

建立了钯催化的三组分串联反应，用于各种三或四取代乙烯基硅烷的立体选择性组装。该方法通过将由1-溴-2-碘苯和N-甲苯磺酰基hydr酮原位生成的邻-乙烯基溴苯进行二甲硅烷基化，从而能够构建两个C-Si键和两个CC键。更重要的是，通过将一系列芳基碘化物和N-甲苯磺酰generated生成的邻乙烯基溴苯转化为乙烯基硅烷，进一步证明了该方案的底物范围。
