  • N-Heterocyclic Carbene-Catalyzed Hydrosilylation of Styryl and Propargylic Alcohols with Dihydrosilanes

    Reducing alkenes to tears: Addition of structurally diverse N‐heterocyclic carbenes (NHCs) to silicon allows the reduction of propargylic and styryl alcohols through an organocatalyzed silylation/direct hydride transfer tandem reaction (see scheme). Catalytic turnover is enabled by the switch to and from hypervalent silicon. This provides a new synthetic application of NHC–main group element complexes

  • Iridium Complexes of the Conformationally Rigid IBioxMe<sub>4</sub> Ligand: Hydride Complexes and Dehydrogenation of Cyclooctene
    作者:Simone A. Hauser、Ralf Tonner、Adrian B. Chaplin
    DOI:10.1021/acs.organomet.5b00658
    日期:2015.9.14
    A method for accessing the formally 14 VE iridium(III) hydride fragment fIr(IBioxMe,),(H)(2)}(+) (2), containing the conformationally rigid NHC ligand IBioxMe(4), is reported. Hydrogenation of trans-[Ir(IBioxMe(4))(2)(COE)C1] (1) in the presence of excess Na[BAr4F] leads to the formation of dimeric [fIr(IBioxMe(4))(2)(H)(2)Cl]-[BAr4F] (3), which is structurally fluxional in solution and acts as a reservoir of monomeric 2 in the presence of excess halogen ion abstractor. Stable dihydride complexes trans-[Ir(IBioxMe(4))(2)(2,2'-bipyridine)(H)(2)][BAr4F] (4) and [Ir(IBioxMe(4))3(H)(2)][BAr4F] (5) were subsequently isolated through in situ trapping of 2 using 2,2'-bipyridine and IBioxMe(4), respectively, and fully characterized. Using mixtures of 3 and Na[BAr4F] as a latent source of 2, the reactive monomeric fragment's reactivity was explored with excess ethylene and cyclooctene, and trans-[Ir(IBioxMe(4))(2)(C2H4)(2)][BAr4F] (6) and cis-[1r(IBioxMe(4))(2)(COD)][BAr4F] (7) were isolated, respectively, through sacrificial hydrogenation of the alkenes. Complex 6 is notable for the adoption of a very unusual orthogonal arrangement of the trans-ethylene ligands in the solid state, which has been analyzed computationally using energy and charge decomposition (EDA-NOCV). The formation of 7 via transfer dehydrogenation of COE highlights the ability to partner IBioxMe(4) with reactive metal centers capable of C H bond activation, without intramolecular activation. Reaction of 7 with CO slowly formed trans-[Ir(lBioxMe(4))(2)(CO)(2)] [BAr4F] (8), but the equivalent reaction with bis-ethylene 6 was an order of magnitude faster, quantifying the strong coordination of COD in 7.
