Steric and Electronic Effects in Half-Sandwich Ruthenium Silane σ-Complexes with Si−H and Si−Cl Interligand Interactions
摘要:
The Cp ring is found to exert a primarily electronic effect on the strength of Si-H interaction in silane sigma-complexes Cp((Pr3P)-P-i)RuCl(eta(2)-HSiClR2). Complexation of chlorosilanes HSiClR2 is supported ky an additional RuCl center dot center dot center dot SiCl interaction.
This paper reports facile preparation of half-sandwich trihydrido complexes of ruthenium based on the reactions of the readily available precursors [Cp(R3P)Ru(NCCH3)(2)][PF6] With LiAlH4. The target complexes were characterized by spectroscopic methods and X-ray structure analysis of Cp((PhPr2P)-P-i)RuH3. (c) 2007 Elsevier B.V. All rights reserved.
