(orcid)0000-0001-8977-6734 C-C Bond Activation of the NHC Ligand of an Osmium-Amido Complex 2010 Treatment of (η6-p-cymene)OsCl2(IPr) (1, IPr = 1,3-bis(2,6-diisopropylphenyl)imidazolylidene) with AgBF4 in acetonitrile leads to [(η6-p-cymene)Os(CH3CN)2(IPr)][BF4]2 (2), which reacts with aniline and cyclohexylamine to afford [(η6-p-cymene)Os(═NHR)(IPr)]BF4 (R = Ph (3), Cy (4)). Complexes 3 and 4 have also been prepared by addition of nBuLi to tetrahydrofuran solutions of the amine compounds [(η6-p-cymene)OsCl(NH2R)(IPr)]BF4 (R = Ph (6), Cy (7)). Complex 4 decomposes in tetrahydrofuran at 100 °C and in the presence of H2O to give cyclohexanone, propane, and [η6-p-cymene)tiebar above startOs{tiebar below startCCHCHCHC(iPr)tiebar below endCtiebar below startNCHCHN(C6H3iPr2)tiebar below endtiebar above endC}(NH3)]BF4 (8). In dichloromethane at 50 °C, 4 evolves to [(η6-p-cymene)OsH(NH═tiebar above startCCH2CH2CH2CH2tiebar above endCH2)(IPr)]BF4 (9), which also gives 8 in tetrahydrofuran at 100 °C and in the presence of H2O. On the basis of these transformations, a mechanism for the formation of 8 is proposed.
