  Hydrido iridium(III) complexes of azoaromatic ligands. Isolation, structure and studies of their physicochemical properties

  摘要：

  Reactions of 2-(arylazo)pyridine (La-c) with [IrCl3(PPh3)(2)] in two different solvents, viz. ethanol and toluene are reported. In refluxing toluene two new isomeric (mer and fac geometries) iridium complexes, having molecular formula [IrCl3(PPh3)(L)] (1 and 2) have been isolated. The reaction in refluxing ethanol yielded two new hydrido complexes of molecular formula [IrHCl2(PPh3)(L)] (3) and [IrHCl(PPh3)(2)(L)]Cl (4) along with the compound 2. All the complexes have been thoroughly characterized by NMR, UV-Vis spectroscopy, cyclic voltammetry and X-ray crystallographic analysis. The H-1 NMR spectra of the hydrido complexes 3 and 4 showed a doublet and a triplet signals at delta -20.43 and -14.82 respectively due to coupling with magnetically equivalent phosphorous nuclei. Strong trans influence of the pi-acceptor ligands guided the X-ray structural parameters; bonds trans to the these ligands are unusually long. Similar elongation effect was also noted for the bonds trans to the coordinated hydrido ligand. UV-Vis-NIR spectrum consisted of multiple transitions in the UV and visible regions. Cyclic voltammetry of each of these complexes has exhibited a reductive response between -0.25 and -0.55 V, which has been assigned to azoligand reduction. The compound 3, however, showed a quasireversible oxidative wave near 1.45 V, due to Ir-III/Ir-IV couple. (C) 2011 Elsevier B. V. All rights reserved.

  work, the reactions of iodine(iii) reagents (PhI(L)2: L = pyridine, acetate (OAc−), triflate (OTf−)) with iridium(i) and rhodium(i) complexes (Vaskas’s compound, Wilkinson’s catalyst, and bis[bis(diphenylphosphino)ethane]rhodium(i) triflate) are reported. In all cases, the reactions resulted in two-electron oxidation of the metal complexes. Mixtures of products were observed in the reactions of Iiii
