Plasma from the Antarctic toothfish, Dissostichus mawsoni, a member of the advanced teleost Nototheniidae family, was analysed. Agarose gel electrophoresis showed a major diffuse anionic protein that bound [14C]palmitic acid but not 63Ni2+, and two more cationic proteins that bound 63Ni2+ but no...
γ-Al2O3-supported nickel phosphides (mNi-Pn) were prepared by the TPR method and tested for the deoxygenation of methyl laurate to hydrocarbons. The effects of the P/Ni ratio (n = 1.0–2.5) and Ni content (m = 5–15 wt.%) in the precursors on their structure and performance were investigated. N...
Early studies on dietary nickel deprivation found decreased reproduction rate in pigs and decreased insemination and conception rates in goats. Studies from our laboratory demonstrated that nickel deprivation impaired male reproductive function of rats. A physiological amount of nickel modulates...
The hydrodeoxygenation (HDO) of anisole was performed with Ni catalysts supported on SBA-15 silica and protonated titanate nanotubes (PTN), in order to determine the effect of the support’s nature and the method of incorporation of Ni species on the catalytic activity and selectivity in HDO. Ca...
Nickel exposure is associated with changes in cellular energy metabolism which may contribute to its carcinogenic properties. Here, we demonstrate that nickel strongly represses mitochondrial fatty acid oxidation—the pathway by which fatty acids are catabolized for energy—in both primary human...
SAPO-11 zeolite-supported PtSn bimetallic catalysts (PtSn/SAPO-11) were prepared using a co-impregnation method for simultaneous selective hydrodeoxygenation of methyl palmitate and isomerization of deoxygenated hydrocarbons. The PtSn catalyst exhibited high isomerization activity and hydrodeoxy...
In this paper, bulk and MCM-41-supported Ni2P catalysts were synthesized by the one-step direct reduction of metal phosphate precursors. The role of cations and anions in the synthesis of Ni2P was studied. Catalytic properties for the hydrodeoxygenation (HDO) of methyl palmitate were first inves...
The synthesis and biological evaluation of novel human A-FABP inhibitors based on the 6-(trifluoromethyl)pyrimidine-4(1H)-one scaffold is described. Two series of compounds, bearing either an amino or carbon substituent in the 2-position of the pyrimidine ring were investigated. Modification of ...
Studies have been made of the flammability [expressed in terms of the limiting oxygen index (LOI)] and the smoke-forming tendency [expressed in terms of the maximum smoke density (Ds)] of systems containing widely varying proportions of an acrylonitrile-butadiene-styrene terpolymer (ABS), decabr...
Flame retardance and smoke suppression have been studied in three systems containing acrylonitrile-butadiene-styrene terpolymer, decabromobiphenyl, and (a) commercial metastannic acid, (b) laboratory-prepared metastannic acid and (c) anhydrous tin(IV) oxide. Values of limiting oxygen index and s...
Five new cadmium(II) coordination polymers [Cd2(L)2Cl2]n·nH2O (1), [Cd(L)Cl(H2O)]n·n[Cd(HL)Cl2]·nH2O (2), [Cd3(L)(1,4-bdc)2.5]n·4nH2O (3), [Cd2(L)(HL)(1,3,5-btc)]n·2nH2O (4), [Cd2(L)2(SO4)]n·2nH2O (5) (HL = 4′-(3-carboxyphenyl)-2,2′:6′,2″-terpyridine, H2(1,4-bdc) = benzene-1,4-dicarbox...
Thioselenophosphinic acids, R2P(Se)SH, generated in situ from secondary phosphine sulfides and elemental selenium, easily add to various vinyl ethers (equimolar ratio, 100 °C, 1,4-dioxane, up to 40 min) to give earlier unknown S- and Se-[1-(organyloxy)ethyl]thioselenophosphinates, i.e., R2P(Se)...
Catalytic hydrogenation is one of the most powerful transformations available in synthetic chemistry; there have been three Nobel Laureates rewarded for their work in the field. Despite the advances in substrate scope and the development of enantioselective versions of this transformation, vinyl...
Methods for preparation of phosphine, primary and secondary phosphines, primary and secondary diphosphines, phosphine–boranes, and primary and secondary phosphine–boranes and their characteristic reactions, namely—alkylation, oxidation, addition reactions, substitution reactions, cross-coupli...
The regiospecific addition of secondary phosphine sulfide and phosphine selenide to alkyl vinyl tellurides proceeds under radical initiation (AIBN, 65–70 °C, 2.5–3.5 h) to afford the anti-Markovnikov adducts, (2-alkyltellanylethyl)phosphine chalcogenides, in 86–99% yields.
Phosphine, generated from red phosphorus in the system KOH–H2O–toluene, reacts with vinyl ethers under radical initiation (AIBN, dioxane, 78–80 °C, atmospheric pressure) to give tris(2-organyloxyethyl)phosphines, which are transformed to the corresponding phosphine chalcogenides (in up to 73...
Phosphine-arenesulfonate ligands that contain 1-3 methoxy substituents on the benzo linker, P(2-OMe-Ph)2(2-SO3Na-5-OMe-Ph) (Na[1a]), P(2-MeO-Ph)2(2-SO3Na-4,5-(OMe)2-Ph) (Na[1b]) and P(2-MeO-Ph)2(2-SO3Li-3,4,5-(OMe)3-Ph) (Li[1c]) were synthesized and isolated in 52–85% yield. Reaction of Na[1a,b...
MnIII-catalyzed functionalization of vinyl azides via phosphorylation was developed to synthesize various β-keto phosphine oxides in high yields. The transformation is operated in mild conditions and tolerant of a range of functional groups. Control reaction indicates that the reaction mechanis...
Efficient and modular syntheses of chiral 2-(2-hydroxyaryl)alcohols (HAROLs), novel 1,4-diols carrying one phenolic and one alcohol hydroxyl group, have been developed which led to generation of a small library of structurally diverse HAROLs in enantiomerically pure form. Of the different HAROLs...
tert-Butyl acetate (TBAc) is an industrial chemical with potential uses as a degreaser and in architectural coatings. Limited chronic toxicity data exist for TBAc. However, acute inhalation exposure data are available for TBAc. Additionally, TBAc has been demonstrated to be substantially metabol...
