Formation of an agostic bond by protonation. Characterization by NMR spectroscopy of [(μ-H)3M3(μ3-η 2-HCR)(CO)9][SO3CF3] (M = Ru, R = Et, CHPhCH2Ph; M = Os, R = Me)

Protonation of (μ-H)3M3(μ3-CX)(CO)9 (M = Ru, X = Et, CHPhCH2Ph; M = Os, X = Me) in HSO3CF3 solution yields [(μ-H)3M3(μ3-η 2-HCR)(CO)9]+, in which the proton has been shown by 1H and 13C NMR spectroscopy to add across a C-M edge. The agostic hydrogen is fluxionally exchanged among all three C-M bonds but does not exchange with the bridging hydrides. These protonated clusters prove to be more susceptible to reductive elimination of CH3X than their neutral precursors. When M = Ru and X = H, Cl, Br, and Ph, addition of acid causes immediate cluster decomposition. When X = Ph and CHPhCH2Ph, the reductive-elimination products toluene and 1,2-diphenylpropane have been identified.
