New Iridathiaboranes with Reversible Isonido ↔ Nido Cluster Flexibility
09-08-2010 | Jonathan Bould; Carmen Cunchillos; Fernando J. Lahoz; Luis A. Oro; John D. Kennedy; Ramón Macías, Inorganic Chemistry, 2010
The reaction between [IrCl(CO)(PMe3)2] and the Cs[arachno-6-SB9H12] salt in CH2Cl2 yields pale-yellow 11-vertex [8,8,8-(CO)(PMe3)2-nido-8,7-IrSB9H10] (4). Reaction of this CO-ligated iridathiaborane with Me3N═O affords pale-yellow 11-vertex [1,1,1-(H)(PMe3)2-isonido-1,2-IrSB9H9] (6), which is ...
Hypervalent Adducts of Chalcogen-Containing peri-Substituted Naphthalenes; Reactions of Sulfur, Selenium, and Tellurium with Dihalogens
09-08-2010 | Fergus R. Knight; Amy L. Fuller; Michael Bühl; Alexandra M. Z. Slawin; J. Derek Woollins, Inorganic Chemistry, 2010
A range of structurally diverse compounds 1−15 {Nap[SPh]2·Br4 (Nap = naphthalene-1,8-diyl); Nap[SePh][EPh]·Br4 (E = Se, S); Nap[SePh]2·I2; Nap[SePh][EPh]·3/2I2 (E = Se, S); Nap[TePh][G]·X2 (G = SePh, SPh, Br, I; X = Br, I); and [Nap(PPh2OH)(SPh)]+Br3−} formed from the reactions between ...
Oxidation of methylphenyl sulfide with hydrogen peroxide in the presence of crown ethers and their complexes with amino acids
07-08-2010 | A. V. Tarakanova, M. Kh. Baishev, E. V. Rakhmanov, S. V. Kardashev, A. V. Anisimov, Theoretical Foundations of Chemical Engineering, 2010
The oxidation of methylphenyl sulfide, benzothiophene, and dibenzothiophene with hydrogen peroxide in the presence of crown ethers was studied. The major product of the oxidation was methylphenyl sulfoxide. The reaction was retarded by the addition of amino acids, which formed 1: 1 complexes ...
Formation and distribution of nitrogen oxides in the production of sulfuric acid by the contact method
07-08-2010 | V. V. Igin, Yu. V. Filatov, V. S. Sushchev, A. A. Zhukova, A. I. Mikhailichenko, N. V. Levin, Theoretical Foundations of Chemical Engineering, 2010
The formation and distribution mechanisms of nitrogen oxides as a part of the technological chain of sulfuric acid systems operating in industrial enterprises with the use of sulfur-containing raw materials (sulfur, hydrogen sulfide, and black sulfuric acid) have been investigated. The ...
Chiral sulfur derivatives in the allylation of acyl hydrazones: C2-symmetric bis-sulfinamides as enhanced chiral organic promoters.
06-08-2010 | Inmaculada Fernández; Ana Alcudia; Beatrice Gori; Victoria Valdivia; Rocío Recio; María Victoria García; Noureddine ..., Organic & Biomolecular Chemistry, 2010
Inmaculada Fernandez, Ana Alcudia, Beatrice Gori, Victoria Valdivia, Rocio Recio, Maria Victoria Garcia, Noureddine Khiar (Paper from Org. Biomol. Chem.) Inmaculada Fernandez, Org. Biomol. Chem., 2010, DOI: 10.1039/c0ob00078g To cite this article before page numbers are assigned, use the ...
New sulfur-oxygen mixed-donor ligand N,N'-dimethyl-piperazine-3-oxo-2-thione (Me2pipto) and its Ni(II) and Fe(II) complexes
06-08-2010 | Luca Pilia; Flavia Artizzu; Davide Espa; Luciano Marchiò; Maria Laura Mercuri; Angela Serpe; Paola Deplano, Dalton Transactions, 2010
Luca Pilia, Flavia Artizzu, Davide Espa, Luciano Marchio, Maria Laura Mercuri, Angela Serpe, Paola Deplano (Communication from Dalton Trans.) Luca Pilia, Dalton Trans., 2010, DOI: 10.1039/c0dt00803f To cite this article before page numbers are assigned, use the DOI form of citation ...
Density Functional Theory Study of Sulfur Adsorption at the (001) Surface of Metal-Rich Nickel Phosphides: Effect of the Ni/P Ratio
05-08-2010 | David Fuks; Dima Vingurt; Miron V. Landau; Moti Herskowitz, Journal of Physical Chemistry C, 2010
A significant increase of the sulfur uptake by NixP with an increasing Ni to P ratio from 2 to 3 was reported recently in ultradeep adsorption desulfurization (ADS) of diesel fuel. It corresponded to increased NixP surface coverage, while no bulk Ni−P−S phases were identified. Density ...
Computational Tests of Quantum Chemical Models for Structures, Vibrational Frequencies, and Heats of Formation of Molecules with Phosphorus and Sulfur Atoms
05-08-2010 | David K. Hahn; Krishans S. RaghuVeer; J. V. Ortiz, Journal of Physical Chemistry A, 2010
The Gaussian-n, complete basis set, and Weizmann-1 quantum chemical models for heats of formation are applied to a set of molecules with relevance to the combustion or pyrolysis of chemical warfare materials. Most of these models generate standard deviations from experiment that are less than ...
Extreme ultraviolet (EUV) degradation of poly(olefin sulfone)s: Towards applications as EUV photoresists
04-08-2010 | Kirsten, Lawrie , Idriss, Blakey , James, Blinco , Roel, Gronheid , Kevin, Jack , ..., Radiation Physics and Chemistry, 2010
Poly(olefin sulfone)s, formed by the reaction of sulfur dioxide (SO2) and an olefin, are known to be highly susceptible to degradation by radiation and thus have been identified as candidate materials for chain scission-based extreme ultraviolet lithography (EUVL) resist materials. In order ...
Elucidation of the Functional Metal Binding Profile of a CdII/PbII Sensor CmtRSc from Streptomyces coelicolor
03-08-2010 | Yun Wang; John Kendall; Jennifer S. Cavet; David P. Giedroc; John Kendall; Jennifer S. Cavet; David P. Giedroc, Biochemistry, 2010
Metal homeostasis and resistance in bacteria is maintained by a panel of metal-sensing transcriptional regulators that collectively control transition metal availability and mediate resistance to heavy metal xenobiotics, including AsIII, CdII, PbII, and HgII. The ArsR family constitutes a ...
