  Cyanide as a versatile Lewis base ligand at a dinitrogen-binding iron(II) centre: mono- and heteronuclear adducts

  摘要：

  The ligated cyanide in trans-[FeH(CN)(dppe)(2)] is activated towards aroylation, alkylation and addition of various transition metal Lewis acids, in particular [WCl4(PPh3)(2)], [ReOCl3(PPh3)(2)], [PdCl2(PPh3)(2)] and [PtCl(Ph)(PPh3)(2)], to give, in the former case, mononuclear isocyanide complexes and, in the latter case, heteronuclear adducts with bridging cyanide. Their syntheses and spectroscopic characterisation are presented, as well as results of the X-ray diffraction analyses of a trinuclear complex with the {Fe-Cequivalent toN-W-Nequivalent toC-Fe} unit and of the parent cyano trans-[FeH(CN)(dppe)(2)] complex. The cyanide bridge allows the electronic communication between the metal centres as indicated by a cyclic voltammetric study. (C) 2003 Elsevier Science B.V. All rights reserved.

  tetradentate ligand P(C6H4SH-2)3(H3L3) reacted with precursors containing Ru, Os and Rh to give [M(HL3)2]–(M = Ru, Os or Rh) where each HL3 ligand is ligated via P and 2S with one unco-ordinated thiol group. These complexes were oxidised in air to give [M(L32)]n+(M = Ru or Os, n= 0; M = Rh, n= 1) where L32 is a hexadentate ligand formed by the coupling of two L3 through two disulfide bonds.

  The preparation of a series of complexes [M(N2)2(p-XC6H4)2PCH2CH2P(C6H4X-p)2}2](M = Mo or W) is described. The variation of oxidation potential with phosphine substituents suggests that the electronic structures involve through-metal conjugation between the phosphine phosphorus and the dinitrogen, which contributes to the strength of the metal–dinitrogen bond.
