Abstract

A disilane that contains two diphenylphosphino moieties, (PhPCH)PhSi-SiPh(CHPPh), was readily synthesized from the reaction of ClPhSi-SiPhCl with (tmeda)Li(CHPPh). Treatment of the thus-obtained disilane with the palladium(0) precursor [Pd(CNBu)] 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.

摘要

一种含有两个二苯基膦部分的乙硅烷，(PhPCH)PhSi-SiPh(CHPPh)，可通过ClPhSi-SiPhCl与(tmeda)Li(CHPPh)反应轻松合成。用钯(0)前体[Pd(CNBu)]处理如此得到的乙硅烷，导致独家形成一种三核钯簇，其中三个钯原子以三角形方式排列。对所得三角形簇进行的单晶X射线衍射分析表明，通过配体骨架的骨架重排形成了新型甲硅烷基磷基螯合配体。
