    摘要:
    A series of the mononuclear nickel(II) complexes 5-16 with N-substituted bis(diphenylphosphanyl) amine RN(PPh2)(2) has been prepared and structurally characterized. Treatment of NiCl2 center dot 6H(2)O with RN(PPh2)(2) [R = CH2Ph, 1; CH(CH3)(2), 2; CH2CH2CH2CH3, 3; CH2CH(CH3)(2), 4] in CH2Cl2/MeOH afforded the mononuclear nickel(II) dichloride complexes [RN(PPh2)(2)]NiCl2 [R = CH2Ph, 5; CH(CH3)(2), 6; CH2CH2CH2CH3, 7; CH2CH(CH3)(2), 8] in 66-71% yields. Further treatment of [RN(PPh2)(2)]NiCl2 with 1,2-ethanedithiol or 1,3-propanedithiol in the presence of triethylamine in CH2Cl2 produced the mononuclear nickel(II) dithiolate complexes [RN(PPh2)(2)] Ni(SCH2CH2S) [R = CH2Ph, 9; CH(CH3)(2), 10; CH2CH2CH2CH3, 11; CH2CH(CH3)(2), 12] and [RN(PPh2)(2)] Ni(SCH2CH2CH2S) [R = CH2Ph, 13; CH(CH3)(2), 14; CH2CH2CH2CH3, 15; CH2CH(CH3)(2), 16] in 41-74% yields, respectively. All the complexes 5-16 have been characterized by H-1 NMR, P-31{H-1} NMR, C-13{H-1} NMR and high resolution MS spectroscopy, and for 3, 4, 6, 9-12 by X-ray crystallography. (C) 2014 Elsevier B.V.

    The synthesis, characterisation of three diiron tetracarbonyl complexes, [Fe2(SCH2)2C(Me)(CH2OR)(PNP)(CO)4] (R = H and PNP = L11: 2; R = H and PNP = L22: 3; R = Ts and PNP = L11: 4) as models for the diiron sub-unit of [FeFe]-hydrogenase are described, where OTs, L11 and L22 are toluenesulfonate, (Ph2P)2NCH2(2-C5H4N) and (Ph2P)2NCH2Ph, respectively. These complexes are fully characterised and the structure of complex 4 is crystallographically determined. Protonation of these complexes with HBF4·Et2O is probed by using infrared and NMR spectroscopies which reveals that no hydride can be formed upon addition of the acid. Instead addition of excess of the acid leads to protonating the N atom of the PNP skeleton, which is a weak base due to participating conjugating interactions with the Fe–Fe centre, as revealed by crystallographic analysis. Electrochemistry of these complexes and their electrocatalytic reduction of protons are also investigated. Our results suggest that the existence of the pendant pyridine group can lower the overpotential for proton reduction but does not seem to enhance electrocatalytic efficiency in our case.

We find that the hydride accepting ability of 1–4 ranges from 71 to 74 kcal/mol in acetonitrile, which should favor a highly exergonic reaction with formate through direct hydride transfer. Formate oxidation was demonstrated at elevated temperatures in the presence of stoichiometric quantities
