Sequential radical addition/cyclization/β-elimination reactions. 3-exo- and 5-exo-cycloaddition reactions of 5-phenylthio-3-pentenyl and 5-phenylthio-3-pentynyl radicals
(Tetrahedron, 1992)
Sequential radical addition/5-exo-cyclization/β-elimination reactions, accomplished by thermally or photolytically induced decompositions of O-acyl derivatives of N-hydroxypyridine-2-thione or other thiohydroxamic esters ...
Investigation of catalytic effects of indigenous minerals in the pyrolysis of Aleksinac oil shale organic matter
(Organic Geochemistry, 1992)
The catalytic effect of indigenous minerals in the pyrolysis of Aleksinac (Yugoslavia) oil shale was studied in this paper. The substrates were prepared by gradual removal of the mineral constituents (carbonates, silicates, ...
Evaluation of the effects of native minerals on the organic matter of Aleksinac oil shale based on the composition of free and bound bitumens
(Organic Geochemistry, 1992)
In order to evaluate the adsorption and catalytic effects of indigenous carbonates and silicates on the organic matter of Aleksinac oil shale, the free and the bound bitumens were isolated and analyzed by organic geochemical ...
Electrogeneration, behaviour and applications of cobalt(III) in perchlorate solutions in acetic acid
(Elsevier, 1992)
Conditions for the electrochemical generation of cobalt(III) in acetic acid-perchlorate media were determined. The current efficiency depended on the current density at the working electrode and on the amounts of water or ...
Thin-layer chromatography on polyacrylonitrile. V. Consideration of separation mechanisms of some aliphatic and aromatic amines
(Journal of Chromatography A, 1992)
The chromatographic behaviour of ten aliphatic and aromatic amines on thin layers of polyacrylonitrile sorbent was investigated using seven aqueous solvent systems. It was established that an increase in the hydrophobic ...
Thin-layer chromatography on polyacrylonitrile. IV. Investigation of the separation mechanisms for tris-(alkylxanthato)cobalt(III) complexes
(Journal of Chromatography A, 1992)
The chromatographic behaviour of six tris(alkylxanthato)cobalt(III) complexes on polyacrylonitrile sorbent thin layers was investigated using four non-aqueous and two aqueous solvent systems. It was assumed that their ...
