Cp(PPhMe2)2RuSiMe3 (9). Complexes 10 and 11 were prepared by the reaction of Cp(PPh2Me)2RuMe with neat hydrosilanes HSiX3 (SiX3 = SiCl3, SiMeCl2) at 100 °C. The effects of the silicon substituents on the spectroscopic properties of 1−11 and the related Cp(PMe3)2RuSiX3 complexes were examined as a function of Tolman's electronic parameter (χi) for the substituents on silicon. The NMR resonance PR3 δ(31P) and the NMR
