A disilane that contains two diphenylphosphino moieties, (Ph₂PCH₂)Ph₂Si–SiPh₂(CH₂PPh), was readily synthesized from the reaction of ClPh₂Si–SiPh₂Cl with (tmeda)Li(CH₂PPh₂). Treatment of the thus-obtained disilane with the palladium(0) precursor [Pd(CN^tBu)₂]₃ led to the exclusive formation of a trinuclear palladium cluster in which three palladium atoms are arranged in a triangular fashion. Single-crystal X-ray diffraction analysis of the obtained triangular cluster revealed that novel silylphosphido chelating ligands were formed via a skeletal rearrangement of the ligand framework.

带有磷化氢悬垂物的乙硅烷中的 Si-Si 键活化产生的三角形钯簇

包含两个二苯基膦基部分A二硅烷，（PH ₂ PCH ₂）PH ₂的Si-SIPH ₂（CH ₂ PPH），被容易地从CLPH反应合成₂的Si-SIPH ₂ Cl可乙二胺（TMEDA）栗（CH ₂ PPH ₂）。用钯(0)前体[Pd(CN ^t Bu) ₂ ] ₃处理由此获得的乙硅烷导致独家形成三核钯簇，其中三个钯原子以三角形方式排列。获得的三角形簇的单晶 X 射线衍射分析表明，通过配体框架的骨架重排形成了新的甲硅烷基磷化螯合配体。
