Synthesis and Reactivity of the Octahedral d6 Parent Amido Complexes TpRu(L)(L‘)(NH2) (Tp = Hydridotris(pyrazolyl)borate; L = L‘ = PMe3, P(OMe)3; L = CO, L‘ = PPh3) and [TpRu(PPh3)(NH2)2][Li]

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 moieties 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 1 H NMR spectroscopy.
