Abstract

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.
