Biodegradation of oil-type pollutants in Danube alluvial sediments (Yugoslavia)
(Inst Lebensmitteltechnologie Analytische Chemie, Freising-Weihenstephan, 2001)
The fate of oil-type pollutants in ground waters from the Danube River (Yugoslavia) alluvion tin the area of an oil refinery) was being surveyed during a long period of time. Based on detailed analyses of extracts (group ...
Steranes and triterpanes as a tool for identification of petroleum-type pollutants in alluvial ground waters (Danube alluvial sediments, Yugoslavia)
(Inst Lebensmitteltechnologie Analytische Chemie, Freising-Weihenstephan, 2001)
In this paper, ground waters from the alluvial Formation of the Danube River were investigated (samples Were taken from boreholes within the Pancevo Oil Refinery, Northern Serbia). The organic substances were extracted, ...
An organic geochemical correlation study of some Drmno depresssion crude oils (southern part of the Pannonian Basin, Yugoslavia) / Organsko-geohemijska korelacija nekih nafti depresije Drmno (južni deo panonskog basena, Jugoslavija)
(Serbian Chemical Soc, Belgrade, 2001)
The results of an investigation of crude oils originating from the Sirakovo and Bradarac-Maljurevac localities (southern part of the Pannonian Basin) are reported in this paper. The aim was to estimate the organic geochemical ...
The Fe(III) complexes with a doubly deprotonated polydentate acylhydrazone: crystal structure of the first diamagnetic mu-oxo-diiron(III) complex
(Elsevier Science Sa, Lausanne, 2001)
The synthesis of two Fe(III) complexes with a doubly deprotonated polydentate of the acylhydrazone class is described. The first complex was obtained by hydrolyzing the previously synthesized high-spin pentagonal-bipyramidal ...
Ni(II) complexes with neutral and dianionic form of 2,6-diacetylpyridine bis(acylhydrazones). Crystal structure of bis[dioxo-2,6-pyridinediylbis(ethylidyne-1-hydrazinyl-2-ylidene) diacetic acid]nickel(II) perchlorate
(Elsevier Science Bv, Amsterdam, 2001)
The octahedral Ni(II) complex with dioxo-2,6-pyridinediylbis(ethylidyne-1-hydrazinyl-2-ylidene)diacetic acid (H(2)dapoamh) was synthesized and X-ray analysis confirmed the tridentate coordination for the neutral ligand. ...
Synthesis and antiproliferative activity of epoxy and bromo compounds derived from estrone
(Pergamon-Elsevier Science Ltd, Oxford, 2001)
Based on biological properties of epoxyquinols from natural sources, bromo and epoxyquinols derived from estrone were synthesized and screened against Fem-X. HeLa and K-562 cell lines. Evidence was found that the bromine ...

Stereo- and regiocontrol of electrophile-initiated rearrangement of push-pull 5-substituted 4-oxothiazolidine derivatives
(Pergamon-Elsevier Science Ltd, Oxford, 2001)
Regioselective a-bromination of (Z)-5-substituted-2-alkylidene-4-oxothiazolidine derivatives affords, under mild experimental conditions, vinyl bromides 3 in good yields. They undergo rearrangement providing a highly ...
Mixed cobalt(III) complexes with aromatic amino acids and diamine. Part II. Synthesis and configuration of (1,2-diaminoethane)bis(L-tyrosinato)-cobalt(III)complex diastereomers. The crystal structure of the Delta-C-1-cis(O) diastereomer
(Gordon Breach Publishing, Taylor & Francis Group, Philadelphia, 2001)
In the reaction of trans-[CoCl2(en)(2)](+) with L-tyrosine all six theoretically possible diastereomers of the (1,2-diaminoethane)bis(L-tyrosinato)cobalt(III) complex were formed. The following five were isolated: Delta ...
Introduction of a methyl group in alpha- or beta-position of 1-heteroarylethyl-4-phenyl-piperazines affects their dopaminergic/serotonergic properties
(Wiley-V C H Verlag Gmbh, Weinheim, 2001)
1-(2-Heteroarylalkyl)-4-phenylpiperazines containing methyl group in either the alpha- or the beta-position of the side alkyl chain were synthesized as racemic mixtures. They were evaluated for in vitro binding affinity ...
