The water-soluble iridium(III) complexes [CpIr(PTA)Cl2] (1) and [CpIr(PTA)2Cl]Cl (2) (PTA = 1,3,5-triaza-7-phosphaadamantane) have been synthesised and characterised by spectroscopy and X-ray crystallography. The complexes were evaluated as catalyst prec ...
The iodocarbonyl monomer [PtI2(CO)2] 7 promotes the iridium catalyzed carbonylation of methanol to acetic acid at low water contents. Studies based on low pressure or high pressure NMR and the use of labeled reactants were cond ...
The catalytic activity of the iridium complexes involved in methanol carbonylation is significantly enhanced when the carbonyliodoplatinum dimer [PtI2(CO)]2 (10') is added to the reaction mixt. Under CO this complex readily affords th ...
The synthesis of [PPN][IrRu3(CO)13] and [PPN][IrOs3(CO)13] from the reaction of [PPN][Ir(CO)4] with M3(CO)12 (M = Ru or Os) is discussed. [PPN][IrRu3(CO)13] is a red-brown microcryst. powder, while [PPN][IrOs3(CO)13] is an orange-red microcryst. powder. Bo ...
A review with refs. concerning electrochem. oxidn. of orgs. in aq. media on iridium oxide and synthetic diamond based electrodes is presented. Effect of nature of electrode material influence on selectivity and efficiency of this process is considered. The ...
A series of ruthenium, osmium and rhodium complexes utilizing pta, (1,3,5-triaza-7-phosphatricyclo-[3.3.1.1]decane) and pta-Me+, its N-methyl derivative, have been synthesized. Their characterization by 1H and 31P NMR spectroscopy, ESI-MS and single crysta ...
Mechanical spectroscopy measurements were performed on decagonal quasicrystalline Al-Cu-Fe-Cr coatings of three different thicknesses deposited on a mild steel substrate. The mechanical loss spectra indicate that the internal friction is mostly caused by t ...
Epoxy-functionalised hyperbranched polymers (HBP) were combined with aminosilanes to form coatings and their effect on the practical adhesion between galvanised steel and polyethylene was investigated. It was shown that HBPs were initially soluble in silan ...
The basic aqueous coordination chemistry of Ru-II has been studied using the catalytically important TPPTS phosphine (TPPTS = trisodium salt of 3,3 ',3 ''-phosphinetriylbenzenesulfonic acid) and small gas molecules (H-2, CO, N-2) as ligands. As a result, n ...
A new series of iridium(III) mixed ligand complexes TBA[Ir(ppy)2(CN)2] (1), TBA[Ir(ppy)2(NCS)2] (2), TBA[Ir(ppy)2(NCO)2] (3), and [Ir(ppy)2(acac) (4) (ppy = 2-phenylpyridine; acac ...
