  A CO-Derived Iron Dicarbyne That Releases Olefin upon Hydrogenation

  摘要：

  An iron diphosphineborane platform that was previously reported to facilitate a high degree of N-2 functionalization is herein shown to effect reductive CO coupling. Disilylation of an iron dicarbonyl precursor furnishes a structurally unprecedented iron dicarbyne complex. Several complexes related to this process are also characterized which allows for a comparative analysis of their respective Fe-B and Fe-C bonding. Facile hydrogenation of the iron dicarbyne at ambient temperature and 1 atm H-2 results in release of a CO-derived olefin.

  H–H and Si–H Bond Addition to Fe≡NNR₂ Intermediates Derived from N₂

  摘要：

  The synthesis and characterization of Fe-diphosphineborane complexes are described in the context of N-2 functionalization chemistry. Iron aminoimides can be generated at room temperature under 1 atm N-2 and are shown to react with E-H bonds from PhSiH3 and H-2. The resulting products derive from delivery of the E fragment to N alpha and the H atom to B. The flexibility and lability of the Fe-BPh interactions in these complexes engender this reactivity.

  E–H Bond Activations and Hydrosilylation Catalysis with Iron and Cobalt Metalloboranes

  摘要：

  An exciting challenge in transition metal catalyst design is to explore whether earth-abundant base metals such as Fe, Co, and Ni can mediate two-electron reductive transformations that their precious metal counterparts (e.g., Ru, Rh, Ir, and Pd) are better known to catalyze. Organometallic metalloboranes are an interesting design concept in this regard because they can serve as organometallic frustrated Lewis pairs. To build on prior studies with nickel metalloboranes featuring the DPB and (DPBMes)-D-Ph ligands in the context of H-2 and slime activation and catalysis (DPB = bis(o-diisopropylphosphinophenyl)phenylborane, (DPBMes)-D-Ph = bis (o-diphenylphosphinophenyl)mesitylborane), we now explore the reactivity of iron, [(DPB)Fe](2)(N-2), 1, and cobalt, (DPB)Co(N-2), 2, metalloboranes toward a series of substrates with E-H bonds (E = O, S, C, N) including phenol, thiophenol, benzo[h]quinoline, and 8-aminoquinoline. In addition to displaying high stoichiometric E-H bond activation reactivity, complexes 1 and 2 prove to be more active catalysts for the hydrosilylation of ketones and aldehydes with diphenylsilane relative to ((DPBMes)-D-Ph)Ni. Indeed, 2 appears to be the most active homogeneous cobalt catalyst reported to date for the hydrosilylation of acetophenone under the conditions studied.

  The well-defined iron(0) complex [(iPrDPBPh)Fe2-(μ-1,2-N2)] (A) reacts with HBpin to afford the complex [(η3-H2iPrDPB)Fe(η3-H2Bpin)] (B) via oxidative addition of the H–B bond. Complex A is an effective pre-catalyst for the hydroboration of a range of olefins in synthetically useful yields (typically >80%) under neat conditions.
