A series of ruthenium(II) N-heterocyclic carbene chelate complexes were prepd. by using bidentate chelating alkene-carbene, thioether-carbene, carboxylate-carbene and bis-carbene ligands. Metalation of 1-R-3-X-imidazolium salts (1-3, R = Me, X = allyl, MeS ...
Enantioselective Rh-promoted activation and 1,4-positional swap of unactivated tetraorganosilanes, e.g., 1-ethyl-3-methyl-3-(2-(trimethylsilyl)phenyl)cyclobutanol (I) to give (1S,3S)-1-ethyl-3-methyl-3((trimethylsilyl)methyl)indanol (II). E.g., reaction of ...
We have investigated Five different poly(ethylene glycol) (PEG, 5 kDa) catechol derivatives in terms of their spontaneous surface assembly from aqueous solution, adlayer stability, and resistance to nonspecific blood serum adsorption as a function of the t ...
The anticancer ruthenium-arene compd. [Ru(η6-C6H5CF3)(pta)Cl2] (pta = 1,3,5-triaza-7-phosphatricyclo[3.3.1.1]decane), termed RAPTA-CF3, with the electron-withdrawing α,α,α-trifluorotoluene ligand, is one of the most cytotoxic RAPTA compds. known. To ration ...
Field and laboratory investigations have been conducted at a former coke plant, discharging to an adjacent river, in order to assess pollutant attenuation in a contaminated alluvial aquifer. Various organic (BTEX, PAHs, mineral oils) and inorganic (As, Zn, ...
The reaction of (cymene)RuCl2 (1) with PCY3 was investigated using different stoichiometries and reaction conditions. Whereas a mixture of complex 1 and 2 equiv of PCy3 in methanol gave the known adduct [(cymene)Rucl(2)(PCy3)] (3) along with the phosp ...
Organic acids are part of assimilable organic carbon (AOC) formed from natural organic matter (NOM) during ozonation for drinking water production. To elucidate the formation of organic acids, phenol as surrogate compound for NOM was ozonated while suppres ...
This paper presents the evaluation of different adsorbents for the improvement of the performances of a gas preconcentrator by targeting the adsorption of a large range of volatiles organics compounds (VOCs) The objectives of this work are to find the adeq ...
The reduction potentials of the title compounds 4 have been measured by cyclic voltammetry. The effect of the substituents has been evaluated by using a linear free energy relationship treatment, thus evidencing that the present ortho-substituents affect t ...
The oxidation of iodide by synthetic birnessite (delta-MnO2) was studied in perchlorate media in the pH range 4-8. Iodine (I-2) was detected as an oxidation product that was subsequently further oxidized to iodate (IO3-). The third order rate constants, se ...
