New mercury organic compounds with 1-3 metal centers and different substituents were synthesized as anion-selective ionophores. They were incorporated into solvent polymeric membranes, and the selectivity, slope of response, response time, emf repeatabilit ...
The behavior of arsenite (AsIII), arsenate (AsV), monomethylarsonate (MMA), dimethylarsinate (DMA), arsenobetaine (AsB) and arsenocholine (AsC) in pyrolytic graphite coated graphite (pyrocoated) tubes was studied. The influence of a tungsten carbide coatin ...
Bromide promoted decompn. of tert-Bu bromide in the presence of triphenylphosphine gives, besides isobutene, hydrogen(triphenyl)phosphonium bromide. When heated to approx. 150 DegC in the presence of xylene, the latter salt liberates hydrogen bromide which ...
High-iron sediments in North Haiwee Reservoir (Olancha, CA), resulting from water treatment for removal of elevated dissolved arsenic in the Los Angeles Aqueduct system, were studied to examine arsenic partitioning between solid phases and porewaters under ...
Ruthenium(II)-arene diphosphine complexes are shown to be effective precursors for the catalytic hydrogenation of the C=C bond in an aqueous biphase using molecular hydrogen as the hydrogen source. A mechanistic study performed in water, utilizing high gas ...
A novel C-Nafton/Fe-ion structured fabric capable of mediating Orange II decomposition in Fenton-immobilized photoassisted reactions is presented. The catalyst preparation requires the right balance between the amount of the Nafion necessary to protect the ...
As a consequence of inherently weak interactions between the chloride anion and the 1-butyl-3-methylimidazolium cation (ca. 15 kJ/mol), chloride dissociation from a transition-metal complex can be thermodynamically disfavored in ionic liquids. Therefore, w ...
With a view to develop drugs that could resist hydrolysis in aq. media,organometallic arene-capped ruthenium(II) 1,3,5-triaza-7-phosphatricyclo[3.3.1.1]decane (RAPTA) complexes bearing chelating carboxylate ligands have been prepd. and studied. The new com ...
The hydrogenation of benzene and other arene substrates under biphasic conditions is evaluated using the catalyst precursor Ru(eta(6)-C10H14)(pta)Cl-2 (pta = 1,3,5-triaza-7-phosphaadamantane) immobilised in water and 1-alkyl-3-methylimidazolium tetrafluoro ...
