Theoretical studies of inorganic and organometallic reaction mechanisms 13: Methane, ethylene, and acetylene activation at a Cationic Iridium Center
(ACS Symposium Series / American Chemical Society, 1999)
The oxidative-addition/reductive-elimination (OA/RE) reactions of methane, ethylene and acetylene with the CpIr(PH3)(CH3)+ complex are investigated by ab initio methods and density functional theory (DFT). The calculated ...
Isolation and partial characterization of a lectin from the marine sponge Crambe crambe
(Journal of the Serbian Chemical Society, 1996)
A lectin was isolated from the marine sponge Crambe crambe. The lectin is a monomeric glycoprotein with relative molecular mass of 14000. It agglutinates sheep and human red blood cells. The agglutination was found to be ...
The preparation of N-alkyl acyclic imides
(Journal of the Serbian Chemical Society, 1996)
An optimized method for the preparation of a little known class of compounds, acyclic imides, is described. First, the N-metalation of selected secondary am des was examined, using various bases and solvents. The most ...
A kinetic investigation of the tris(4-morpholinecarbodithionato-S,S') cobalt(III) complex formation by the intralattice and interlattice reactions
(Thermochimica Acta, 1993)
The kinetics of tris-(4-morpholinecarbodithionato-S,S) cobalt(III) formation by the intralattice and interlattice reactions of hexaaminecobalt(III) cation with dithiocarbamato anion was investigated under isothermal ...
Biological activities of avarol derivatives, 1. Amino derivatives
(American Chemical Society, 1990)
Nine amino derivatives, compounds 3-11. of avarone were synthesized. Their antibacterial and cytotoxic activities are evaluated, and the results of a prescreen for antitumor effects are reported.
Oil/oil correlation based on gas chromatographic/mass spectrometric analysis of polycyclic biomarkers
(Rapid Communications in Mass Spectrometry, 1990)
Polycyclic biomarkers such as steranes, diasteranes and tri‐, tetra‐ and pentacyclic terpanes in the hydrocarbon fraction of oils were studied by gas chromatographic/mass spectrometric (GC/MS) analysis in order to correlate ...
Preparation and characterization of meridional isomers of uns-cis-(ethylenediamine-N,N'-di-3-propionato)cobalt(III) complexes with some β-amino acids
(Journal of the Serbian Chemical Society, 1996)
The meridional geometrical isomers of uns-cis-(ethylenediamine-N,N ′-di-3-propionato)cobalt(III) complexes with anions of β-alanine, β-amino-buteric and β-amino-isobuteric acids were prepared in the reaction of sodium ...
Influence of depyritization on NMR relaxation parameters of Aleksinac oil shale kerogen
(Elsevier Sci Ltd, Oxford, 1998)
Parallel proton and cross-polarization/magic-angle spinning (CP/MAS) nuclear magnetic resonance (NMR) relaxation measurements are reported on Aleksinac oil shale kerogen concentrate and pyrite-free kerogen concentrate. ...
Ring closure reaction of 4-tert-butyl-4-penten-1-ol with electrophilic reagents
(Natl Inst Science Communication, New Delhi, 1999)
The reaction of 4-tert-butyl-4-penten-1-ol 3 with some electrophilic reagents (such as mineral acids, mercuric acetate, peracids) has been investigated. It is found that in the acid (H2SO4) catalysed reaction of 3, the ...
The synthesis and characterization of facial and meridional isomers of unsym-cis-(ethylene diamine-N,N '-di-3-propionato)cobalt(III) complexes with natural aliphatic alpha-amino acids containing oxygen and sulfur
(Marcel Dekker Inc, New York, 1999)
In the reaction of sodium unsym-cis-(ethylenediamine-N,N'-di-3-Dropionato)(carbonato)cobaltate(III) dihydrate and the corresponding amino acid (S-serine, S-threonine, S-cysteine and R,S-methionine) at 70 degrees C, both ...
