    摘要:
    据报道,具有氧化还原活性的非纯双酰亚胺吡啶配体的铁配合物可催化未活化的芳烃和芳基卤化物之间的串联CH活化/芳基化反应。第一行过渡金属催化的类似反应已显示涉及基于底物的芳基,而我们的催化体系可能涉及以配体为中心的基团。基于光谱学和反应性研究的初步机理研究,结合DFT计算,我们建议反应可以通过内层CH活化途径进行,这在铁络合物中很少观察到。这种类似双电子的贵金属行为可以通过具有氧化还原活性的非纯双酰亚胺吡啶配体来维持。

    Iron-Catalyzed Formation of 2-Aminopyridines from Diynes and Cyanamides
    摘要:
    Diynes and cyanamides undergo an iron-catalyzed [2 + 2 + 2] cycloaddition to form highly substituted 2-aminopyridines in an atom-efficient manner that is both high yielding and regioselective. This system was also used to cyclize two terminal alkynes and a cyanamide to afford a 2,4,6-trisubstituted pyridine product regioselectively.

    Complexation of hydrated Cu(BF4)2 by 2 molar equivalents of L2R (L2Me = 2,6-bismethyliminomethyl}pyridine, L2Cy = 2,6-biscyclohexyliminomethyl}pyridine, L2But = 2,6-bistert-butyliminomethyl}pyridine) afforded [Cu(L2R)2][BF4]2 (R = Me, 1; Cy, 2; or But, 3) in moderate yields. EPR spectroscopy in solution and the solid state demonstrates that 1 and 2 adopt the expected dy2 − z2}1 electronic ground state, and that the pseudo-Jahn–Teller elongation axis is fluxional in solid 1 and static in solid 2. In contrast, 3 exhibits a dz2}1 ground state by EPR. The crystal structures of 2·MeNO2 and 3·½Me2CO contain rhombic six-co-ordinate copper(II) ions, which differ principally in the length of the Cu–N bonds close to the molecular y axis. Treatment of [Cu(NCMe)4]BF4 with varying ratios of L2R yields [Cu(L2R)2]BF4 (R = Me, 4; Mes, 5; or Cy, 6: L2Mes = 2,6-bis2,4,6-trimethylphenyliminomethyl}pyridine) or [Cu(L2But)}2][BF4]27. The single crystal structure of 5·MeCN shows a flattened tetrahedral copper(I) centre with two bidentate L2Mes ligands. Reaction of hydrated Cu(ClO4)2 with 2 molar equivalents of L3 (1,3-bispyridin-2-yl}pyrazole) yields [Cu(L3)2][ClO4]28, whose crystal structure demonstrates a six-co-ordinate copper(II) ion with long Cu–Npyridine} bonds. Powder EPR spectroscopy demonstrates a dz2}1 ground state for 8 in the solid.

  • Coordination Chemistry and Reactivity of Bis(aldimino)pyridine Nickel Complexes in Four Different Oxidation States

    A series of nickel complexes with potentially redox active bis(aldimino)pyridine ligands [NNN] ([NNN] = 1,1'-(pyridine-2,6-diyl)bis(N-arylmethanimine), where aryl = 2,6-diisopropylphenyl, mesityl, 4-methoxyphenyl, 4-trifluoromethylphenyl, and 3,5-bis-(trifluoromethyl)phenyl) were synthesized, and their properties and reactivities were investigated as a function of the overall oxidation state of the system. (Ni[NNN])(2+) complexes of ligands featuring bulky electron-rich substituents (1a-Br-2 and 1b-Br-2, [NNN] = 1,1' (pyridine -2,6-diyl) bis (N-(2,6-diisopropylphenyl)methanimine) and 1,1'-(pyridine-2,6-diyl)bis(N-mesitylmethanimine), respectively) demonstrated five electrochemical reduction events, the first three of which were quasi-reversible. In contrast, only two quasi-reversible reductions were observed for the less bulky and electron-deficient N-aryl substituents 4-(trifluoromethyDphenyl and 3,5-bis(trifluoromethyl)phenyl. Chemical reduction of la-Br, and lb-Br, with 1 equiv of KC8 or CoCp*(2) forms (Ni[NNN])(0) complexes of the general formula Ni[NNN]Br (2a-Br and 2b-Br). Structural, spectroscopic, and theoretical studies reveal that these complexes feature significant unpaired spin density on the metal, consistent with "nickel(I)" character. This behavior is in contrast with previously reported bis(ketimino)pyridine systems, in which at the (Ni[NNN])(+) state the unpaired electron resided exclusively in the ligand. Further reduction forms a series of (Ni[NNN]) complexes, in which all of the potentially tridentate [NNN] ligands bind via only one iminopyridine unit; the second arm is left unbound in most complexes. Variable temperature NMR spectroscopy demonstrates that bound and unbound arms exchange via a postulated tridentate intermediate. Electrochemical reduction, via three sequential one-electron reductions, of la-Br, and lb-Br, in the presence of CO2/H+ forms an active catalyst for H-2 evolution at a glassy-carbon electrode surface, again emphasizing the unique redox chemistry of the bulky bis(aldimino)pyridine nickel complexes.
