摘要:
The first donor-stabilized [bis(silylene)]ruthenium compex, Cp(Ph3P)Ru(SiMe2---O(Me)---SiMe2), has been synthesized by the thermal reaction of CpRu(Pph3)2Me with HMe2SiSiMe2OMe. The X-ray crystal structure analysis of this complex revealed its distorted-piano-stool structure, containing a RuSi2O four-membered chelate ring with two short Ru-Si bonds and two long Si-O bonds.
