Synthesis and Reactivity of the Octahedral d~6 Parent Amido Complexes TpRu(L)(L')(NH_2) (Tp = Hydridotris(pyrazolyl)borate; L = L' = PMe_3, P(OMe)_3; L = CO, L' = PPH_3) and [TpRu(PPh_3)(NH_2)_2][Li]

摘要

A series of octahedral ruthenium(II) parent amido complexes of the type TpRu(L)(L')(NH_2) (L/L' = neutral and two-electron-donor ligands) and [TpRu(PPh_3)(NH_2)_2][Li] (Tp = hydridotris(pyrazolyl)borate) have been prepared. Preliminary reactivity studies indicate that the amido moieites are highly basic; for example, TpRu(L)(L')(NH_2) complexes deprotonate phenylacetylene at room temperature to form [TpRu(L)(L')(NH_3)][PhC_2] ion pairs, as determined by ~1H NMR spectroscopy.
