2-Alkylidene-4-oxothiazolidine S-oxides: synthesis and stereochemistry
(Oxford : Pergamon-Elsevier Science Ltd, 2013)
A series of 5-unsubstituted and 5-substituted 2-alkylidene-4-oxothiazolidine-S-oxides were synthesized by the sulfur-oxidation with m-CPBA. The stereochemistry of 5-substituted sulfoxides was determined by means of NMR ...
Long term changes in trophic status and environmental parameters of Grlište reservoir, Serbia / Dugoročne promene u trofičkom statusu i ekološkim parametrima akumulacije Grlište, Srbija
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2013)
In the purpose of monitoring the change of trophic status and water quality in the reservoir Grlište, in the period of 20 years, once a month sampling of water was conducted at two places. The obtained results were used ...
Unusual mode of reactivity of 2-alkylidene-4-oxothiazolidine S-oxides under the Pummerer reaction conditions
(Oxford : Pergamon-Elsevier Science Ltd, 2013)
The reactivity of 2-alkylidene-4-oxothiazolidine S-oxides under the Pummerer reaction conditions, using Ac2O, TFAA, SOCl2 and SOBr2 as initiators, has been examined. Almost all reactions proceeded with absolute regioselectivity ...
Magnetic Anisotropy of the C-C Single Bond
(Wiley-V C H Verlag Gmbh, Weinheim, 2013)
Anisotropic effects are broadly used in NMR spectroscopy for structure elucidation. With the development of computational methods it has become possible to quantify the effects and obtain further insight into their origin. ...
H-1 NMR Chemical Shifts of Cyclopropane and Cyclobutane: A Theoretical Study
(American Chemical Society (ACS), 2013)
This study was undertaken in order to rationalize the peculiar H-1 NMR chemical shifts of cyclopropane (delta 0.22) and cyclobutane (delta 1.98) which are shifted upfield and downfield with respect to larger cycloalkanes ...
Electrooxidation of p-nitrophenol on organobentonite modified electrodes
(Elsevier, 2013)
A natural bentonite, modified with different quaternary ammonium cations, hexadecyl trimethylammonium, (HDTMA), dodecyl trimethylammonium (DTMA) and tetramethylammonium (TMA), was used as an electrode material in a ...
Influence of supramolecular structures in crystals on parallel stacking interactions between pyridine molecules
(Wiley-Blackwell, Hoboken, 2013)
Parallel stacking interactions between pyridines in crystal structures and the influence of hydrogen bonding and supramolecular structures in crystals on the geometries of interactions were studied by analyzing data from ...
The choice of the exchange-correlation functional for the determination of the Jahn-Teller parameters by the density functional theory
(Wiley-Blackwell, Hoboken, 2013)
The JahnTeller (JT) parameters for small, aromatic, organic radicals, CnHn (n = 47), bis(cyclopentadienyl)cobalt(II) (cobaltocene), a sodium cluster (Na3), a silver cluster (Ag3), the hexaflurocuprate(II) ion ([CuF6]4), ...
Density functional theory study of the multimode Jahn-Teller problem in the fullerene anion
(Wiley-Blackwell, Hoboken, 2013)
The fullerene anion, C60, within the Ih point group, is a spherical molecule subject to the T circle times h JahnTeller (JT) distortion. The descent in symmetry goes to the three epikernel subgroups, namely D5d, D3d, and ...
In Vitro Antibacterial Activity of Cysteine Protease Inhibitor from Kiwifruit (Actinidia deliciosa)
(Springer, New York, 2013)
The need for replacing traditional pesticides with alternative agents for the management of agricultural pathogens is rising worldwide. In this study, a cysteine proteinase inhibitor (CPI), 11 kDa in size, was purified ...
