Abstract

Treatment of the osmium(II) hydrides Cp^*Os(P-P)H (Cp^* = pentamethylcyclopentadienyl) with methyl trifluoromethanesulfonate (MeOTf) affords osmium(II) triflate complexes with the general formula Cp^*Os(P-P)(OTf), where P-P = bis(dimethylphosphino)methane (dmpm), bis(diphenylphosphino)methane (dppm), or 1,2-bis(dimethylphosphino)ethane (dmpe). The aqua complexes [Cp^*Os(dmpm)(OH₂)][OTf] and [Cp^*Os(dppm)(OH₂)][OTf] are synthesized by the addition of water to the corresponding anhydrous triflates. The complexes Cp^*Os(dppm)(OTf) and [Cp^*Os(dmpm)(OH₂)][OTf] have been examined crystallographically, and all compounds have been characterized by NMR spectroscopy.
