1,3-Migration of phenylthio group in the rearrangement of tertiary cyclopropylmethanols possessing an α-phenylthio group
(Journal of the Serbian Chemical Society, 1996)
The acid catalysed ring opening of tertiary cyclopropylmethanols 1 (R = H, vinyl, Ph), possessing a phenylthio group on the adjacent carbon atom proceeds, regioselectively and homoallylic halides 2 are obtained in 49 - 86% ...
Improved electrochemical epoxidation of cholesterol and avarol dimethyl ether
(Journal of the Serbian Chemical Society, 1996)
Electrochemical epoxidation of cholesterol and avarol dimethyl ether with bromide as heteromediator was performed, and its mechanism discussed. The influence of the solvent, the mediator concentration, and different ...
Ring closure reaction of 4-tert-butyl-4-penten-1-ol and 4-tert-butyl-1-pentanol with lead tetraacetate
(Journal of the Serbian Chemical Society, 1996)
The lead tetraacetate (LTA) oxidation of 4-tert-butyl-4-penten-1-ol (3) in boiling benzene afforded the tetrahydrofuran (THF) acetoxy ether 7 (78%) as the main product, while the acetoxylated tetrahydropyran (THP) ether ...

Biologically active dinuclear complexes of cobalt(II) with a pendant octaazamacrocyclic ligand and pseudohalides
(Serbian Chemical Soc, Belgrade, 1999)
In the three newly-prepared mixed dinuclear penta-coordinated cobalt(II) complexes, with the pendant macrocyclic ligand N,N',N ",N"'-tetrakis(2-pyridylmethyl)-1,4,8,11-tetraazacyclotetradecane (tpmc) and pseudohalides, of ...
GC-MS in organic geochemistry of coal-estimation of the origin and degree of carbonification in coal from the Kosovo basin (Yugoslavia)
(Journal of the Serbian Chemical Society, 1996)
Biological markers in the alkane fraction of coal from the central and southern parts of the Kosovo basin (Yugoslavia) were analyzed by using computerized gas chromatography-mass spectrornetry (GC-MS). The presence of ...
A contribution to the elucidation of oil migration mechanisms through water-wet sediments: Crushed rock environment as example
(Journal of the Serbian Chemical Society, 1996)
In order to gain insight into oil transformations which occur during migration, and to contribute to the elucidation of migration mechanisms in water-wet environments, the content and composition of heavy fuel oil from an ...
GC-MS in crude oil correlation studies - Effects of biodegradation on sterane and terpane maturation parameters
(Journal of the Serbian Chemical Society, 1996)
GC-MS was applied in order to determine the effects of biodegradation on steranes and terpanes in crude oils. Sterane and tcrpane maturation parameters were correlated in 36 crude oils, biodegraded to various degrees (28 ...
Synthesis of 4-oxothiazolidine derivatives containing two exocyclic C=C bonds
(Serbian Chemical Soc, Belgrade, 1999)
Stereodefined thiazolidine derivatives bearing two exocyclic C=C bonds were under mild reaction conditions synthesized from 5-substituted 4-oxothiazolidine precursors via the efficient bromination-dehydrobromination pathway.
Catalytic titrations of silver(I) applying the iodide-catalysed manganese(IV)-arsenic(III) indicator reaction in the presence of sulphuric acid
(Serbian Chemical Soc, Belgrade, 1999)
A new catalytic potentiometric titration method for the determination of silver(I), applying the iodide-catalysed manganese(IV)-arsenic(III) indicator reaction in the presence of sulphuric acid, has been developed. The ...
