  Synthesis and Characterization of Cobalt Complexes with Radical Anionic α-Diimine Ligands

  摘要：

  Three cobalt complexes, [LCo(mu-Cl)](2)center dot THF center dot Et2O (1), [LCo(eta(6)-toluene)] (2), and [LCo](2) (3), where L = [(2,6-iPr(2)C(6)H(3))NC(Me)](2), have been synthesized from reduction of the dichloro cobalt precursor [LCoCl2] by sodium or potassium metal. Single-crystal X-ray diffraction analyses reveal that the complexes display novel structures with the singly reduced form (L center dot-) of the a-diimine ligand: the dichloro-bridged binuclear complex 1, the mononuclear 2 with an eta(6)-coordinated toluene molecule, and the dimer 3 through Co-aryl interactions of two [LCo] units. The compounds were further characterized by EPR and magnetic studies.

  chain-walking hydroboration to create a one-pot, contra-thermodynamic, short- or long-range isomerization of internal olefins to terminal olefins. This dehydroboration occurs by a sequence comprising activation with a nucleophile, iodination, and base-promoted elimination. The isomerization proceeds at room temperature without the need for a fluoride base, and the substrate scope of this isomerization is expanded

  Preliminary results on the preparation of nickel(II) and cobalt(II) complexes containing alpha-diimine ligands using a mechanochemical approach are presented. The solvent-free reaction of [NiBr2(DME)] (DME 1,2-dimethoxyethane) with the appropriate alpha-diimine ligand led to the formation of the expected Ni(II) complexes in very short reaction times and with quantitative yields. The same compounds were also successfully synthesised when NiBr2 was employed. This methodology was extended to the preparation of [Co(alpha-diimine)Cl-2] complexes through the reaction of CoCl2 with different alpha-diimine ligands. These compounds were characterised by XRPD and SCXRD, when possible. The results obtained confirm that mechanochemistry has an enormous potential and that is an effective technique for the synthesis of coordination and organometallic compounds. (C) 2013 Elsevier B. V.
