Oxidation of dibenzothiophene as a model substrate for the removal of organic sulphur from fossil fuels by iron(III) ions generated from pyrite by Acidithiobacillus ferrooxidans / Oksidacija dibenzotiofena kao model-supstrata za izdvajanje organskog sumpora iz fosilnih goriva dejstvom gvožđe(III)-jona generisanog iz pirita pomoću Acidithiobacillus ferrooxidans
(Serbian Chemical Society, 2007)
Within this paper a new idea for the removal of organically bonded sulphur from fossil fuels is discussed. Dibenzothiophene (DBT) was used as a model compound of organicmolecules containing sulphur. This form of ...
Radical reactions of xanthates: Annulation of the cyclopentene ring / Radikalske reakcije ksantata : anelacija ciklopentenovog prstena
(Belgrade : Serbian Chemical Society, 2007)
Homoallylic radicals, generated from the corresponding xanthates, react with terminal alkynes to give cyclopentene derivatives in moderate yields.
Magnetic effects in electrochemistry / Magnetni efekti u elektrohemiji
(Serbian Chemical Society, 2005)
The effect of imposed magnetic fields onto the electrodeposition of magnetic (nickel) and non – magnetic (copper) metals was analysed. Also, magnetic properties of electrochemically obtained nanocontacts were examined. An ...
Synthesis and pharmacological evaluation of several N-(2-nitrophenyl) piperazine derivatives / Sinteza i farmakološko ispitivanje novih derivata N-(2-nitrofenil) piperazina
(Serbian Chemical Society, 2007)
Six newly synthesized heterocyclic (2-nitrophenyl)piperazines, with a specific structure of the heteroaryl group, whichmimics the catechol moiety of dopamine (benzimidazoles and substituted benzimidazoles), were evaluated ...
Intramolecular Barbier reaction in water: Cyclopentane and cyclohexane ring closure / Intramolekulska Barbier-ova reakcija u vodi - sinteza petočlanih i šestočlanih prstenova
(Serbian Chemical Society, 2002)
Zinc or indium promoted intramolecular Barbier reactions of aldehydes containing a suitably positioned allylic or propargylic halide unit afford unsaturated cyclic alcohols in moderate yields.

(Serbian Chemical Society, 2008)
The results of an investigation of the capacitive characteristics of sol-gel-processed titanium- and carbon-supported electrochemically active noble metal oxides, as representatives of porous electrode materials, are ...
Quantitative analysis of sesquiterpene lactone cnicin in seven Centaurea species wild-growing in Serbia and Montenegro using 1H-NMR spectroscopy / Kvantitativna analiza seskviterpenskog laktona knicina u sedam samoniklih biljnih vrsta roda Centaurea, koje rastu u Srbiji i Crnoj Gori, korišćenjem 1H-NMR
(Serbian Chemical Society, 2007)
1H-NMR spectroscopy was applied for the quantitative analysis of cnicin, a bioactive germacranolide type sesquiterpene lactone, in the aerial parts of seven wild-growing Centaurea species collected in Serbia and Montenegro. ...
Regioselectivity of conjugate additions to monoalkyl-1,4-benzoquinones / Regioselektivnost konjugovane adicijena monoalkil-1,4-benzohinone
(Serbian Chemical Society, 2002)
The regioselectivity of the reaction of conjugate addition of thiols amines, methanol and hydrogen chloride with the monoalkyl-1,4-benzoquinones avarone and 2-tert-butyl- 1,4-benzoquinone was investigated. It was shown ...
