Two mechanisms have been proposed for the palladium-catalyzed silylation reaction, both of which account for the formation of reduced arene byproducts. Both the C-X bond of aryl halides and the Si-H bond of silanes are known to undergo oxidative addition to Pd(0) complexes. Thus, two logical mechanisms have been proposed, one with Ar-Pd(II)-X, and the other with R3Si-Pd(II)-H as the key intermediate, respectively.
钯催化的硅烷化反应已有人提出两种机制,二者均导致形成还原性芳烃副产物。已知卤代芳烃的C-X键和硅烷的Si-H键均会氧化加成到Pd(0)复合物。因此就提出了两种合理的机制,分别以Ar-Pd(II)-X和R3Si-Pd(II)-H为关键中间产物。 |
