A series of novel fused 4?-substituted 2,2?:6?, 2??-terpyridine ligands and their ruthenium(ii) complexes were prepared. The unusual 4?-substituents comprised 2,3,4,5-pentaphenylbenzene and its tert-butyl derivative (1 and 2) and the products from oxidative cyclodehydrogenation, i.e. polyaromatic fragments consisting of ten or thirteen fused benzene rings (3 and 4). The syntheses of all the ligands are discussed in terms of the demands and limitations of the Scholl reaction. The optical properties of the ligands, along with the single-crystal X-ray structures of 1 and 2, are presented. The latter show that the pentaphenylbenzene and terpyridine appendages of 1 and 2 are perpendicular in the solid state. Despite the inclusion of the large organic chromophore the absorption and emission properties of the Ru(ii) bis-terpy complexes (of ligands 1, 2 and 3) were found to be comparable to those of [Ru(terpy)2]2+. They are non-emissive at room temperature but emit at 77 K with excited state lifetimes of 11-12 mus.

Double complex salts (DCSs) with [M(NH3)5Cl] 2+ (M = Rh, Ir, Co, Cr, Ru) cations and [PtBr4] 2- anions were prepared in high yields. The salts were two-phase mixtures of the anhydrous and monohydro DCSs. Anhydrous analogues containing [PdBr4]2- anions with M = Cr or Ru were synthesized. All the compounds were characterized using a set of physicochemical methods. The crystal structure of chloropentaamminechromium(III) tetrabromopalladate(II) was solved: space group Pnma, Z = 4, a = 17.068(2) A, b = 8.315(12) A, c = 9.653(14) A. The [M(NH3)5Cl][M’X4] (M = Rh, Ir, Co, Cr, Ru; M’ = Pd, Pt; X = Cl, Br) compounds were shown to be isostructural. The [M(NH3)5Cl][PtBr4] ? H2O monohydrates are isostructural to the [M(NH3) 5Cl][PdCl4] ? H2O monohydrates (space group P21/c, z = 4). The properties of the compounds were comparatively analyzed. The tendencies of the thermal stability of the complexes were elucidated. The thermolysis products of the double complex salts obtained under a helium or hydrogen atmosphere were studied.

In the presence of conventional supported hydrotreating catalysts, substituted benzenes undergo two parallel initial reactions, i.e., hydrogenolysis of carbon sp2-heteroatom bonds and hydrogenation of the aromatic ring. It has been reported that they are suitable model compounds for evaluating the hydrogenolysis vs. hydrogenation activity of these catalysts. Hydroprocessing of substituted benzenes, e.g., aniline, phenol, diphenylsulfide, and chlorobenzene, was conducted in a batch reactor at 280C and 70 bar H2 pressure over unsupported transition metal sulfides, i.e. Co, Ni, Nb, Mo, Ru, Rh, Pd, and W sulfides. Chlorobenzene and diphenylsulfide mainly reacted via initial hydrogenolysis of the carbon-substituent bond, while aniline and phenol reacted via initial hydrogenation of the aromatic ring. The results confirmed the influence of mesomeric effects on the reactivity of organic models toward sulfided catalysts. Quantum chemical calculations indicated that the hydrogenolysis constants correlated with the pi-electron density on the carbon bearing the substituent and with the overall calculated pi-electron transfer between the substituents and the benzene ring. It was assumed that hydrogenolysis of carbon sp2-substituent bonds resulted from the attack by a soft nucleophilic species like a hydride ion on the carbon bearing the substituent.

In a patent, introducing its new discovery.

In this work, results for the electrocatalysis of CO and methanol electro-oxidation are discussed considering the validity of the extrapolation of results obtained in fundamental electrochemical systems to operational low-temperature fuel cells (DMFC). It is concluded that the performance of the catalysts depends not only on obvious parameters, like the composition, but also on the method of preparation, subsequent treatments, and even on the nature of the metal precursors. Furthermore, the results show that parameters of the supported catalyst, like particle size, may not be as important as a uniform distribution of the particles on the support obtained with a clean method of preparation. The conclusion is that much progress is still needed in the understanding of the behaviour of the catalysts, particularly bimetallic and multimetallic catalysts in order to extrapolate results obtained in fundamental systems to practical systems. At present, the only real test of a given catalyst seems to be the evaluation of the performance in an actual fuel cell.

A procedure for the synthesis of mpa h c-[Ru(NO)(NH3) 4(OH)]Cl2 in a nearly quantitative yield (?95%) comprising treatment of a solution of (NH4)2[Ru(NO)Cl 5] with ammonium carbonate at t ?80C was developed. It was found that [Ru(NO)(NH3)4(H2O)]Cl 3?H2O and trans-[Ru(NO)(NH3) 4Cl]Cl2 formed in the reaction of [Ru(NO)(NH 3)4(OH)]Cl2 with hydrochloric acid at various temperatures most often contain some initial hydroxy complex. The former compound is unstable, even at room temperature, it slowly eliminates water and HCl. A procedure for preparing the latter compound in a pure state in 85-90% yield was proposed. The acidity constant of the complex trans-[Ru(NO)(NH 3)4(H2O)]3+ at room temperature (K a = (4 ± 1) × 10-2) was estimated by 14N NMR spectroscopy.

Synthesis and characterization of the dinuclear ruthenium coordination complexes with heteroleptic ligand sets, [Cl(terpy)Ru(tpphz)Ru(terpy)Cl](PF 6)2 (7) and [(phen)2Ru(tpphz)Ru(terpy)Cl] (PF6)3 (8), are reported. Both structures contain a tetrapyrido[3,2-alpha:2?,3?-c:3?,2?-h:2?, 3?-j]phenazine (tpphz) (6) ligand bridging the two metal centers. Complex 7 was obtained via ligand exchange between, RuCl2(terpy)DMSO (5) and a tpphz bridge. Complex 8 was obtained via ligand exchange between, [Ru(phen)2tpphz](PF6)2 (4) and RuCl 2(terpy)DMSO (5). Metal-to-ligand-charge-transfer (MLCT) absorptions are sensitive to ligand set composition and are significantly red-shifted due to more electron donating ligands. Complexes 7-9 have been characterized by analytical, spectroscopic (IR, NMR, and UV-Vis), and mass spectrometric techniques. The electronic spectral properties of 7, 8, and [(phen) 2Ru(tpphz)Ru(phen)2](PF6)4 (9), a previously reported +4 analog, are presented together. The different terminal ligands of 7, 8, and 9 shift the energy of the MLCT and the pi-pi* transition of the bridging ligand. These shifts in the spectra are discussed in the context of density functional theory (DFT). A model is proposed suggesting that low-lying orbitals of the bridging ligand accept electron density from the metal center which can facilitate electron transfer to nanoparticles like single walled carbon nanotubes and colloidal gold.
