Structure and reactivity of steroidal quinones
(Journal of the Serbian Chemical Society, 1997)
The preparation of substituted steroidal A-ring 1,4-quinones by nucleophilic addition results in pronounced regioselectivity at C(2), as confirmed by the X-ray analysis of 2-methoxy-2,5(10)-diene-1,4,17-trione. Conformational ...
The mechanisms of tris(4-morpholinecarbodithioato-S,S′)cobalt(III) complex formation by solid state reaction from ammine cobalt(III) complexes
(Journal of the Serbian Chemical Society, 1997)
In this paper, the solid state reaction, conducted with a mixture of pentaamminechlorocobalt(III) chloride and potassium 4-morpholinecarbodithioate was investigated under isothermal conditions. The reaction proceeds at ...

Cyclization/alkoxy radical fragmentation tandem: An efficient approach to the synthesis of bridged cyclooctane derivatives
(Journal of the Serbian Chemical Society, 1997)
In this paper an efficient synthetic approach to bridged cyclooctanone framework is described, which is based on cyclization/alkoxy radical fragmentation as a tactical combination of reactions. While the hypoiodite reaction ...
Ab initio calculations of the geometries and bonding energies of alkane and fluoroalkane complexes with tungsten pentacarbonyl
(Amer Chemical Soc, Washington, 1997)
Ab initio calculations of the bonding energies of alkanes and fluoromethanes to W(CO)(5) have been performed in several basis sets and at a variety of different levels of electron correlation. The Moller-Plesset second-order ...
Pentagonal bipyramidal complexes of Co(II) with singly- and doubly-deprotonated 2 ',2 '''-(2,6-pyridindiyldiethylidene)dioxamohydrazide - The crystal structure of [diaqua-2 ',2 '''-(2,6-pyridindiyldiethylidene)dioxamohydrazidecobalt(II)] hexahydrate
(Gordon Breach Sci Publ Ltd, Reading, 1997)
This paper reports the first Co(II) complexes with a singly-and doubly-deprotonated H2L ligand (H2L = 2',2'''-(2,6-pyridindiyldiethylidene)dioxamohydrazide belonging to the planar pentadentate class. The complexes were ...

Chemical and electrochemical reductions of some allyl type halides catalyzed by vitamin B-12
(Natl Inst Science Communication & Information Resources-Niscair, New Delhi, 1997)
Chemical and electrochemical reductions of some allyl type halides catalyzed by vitamin B-12 have been studied. Geranyl bromide 1 and methyl (2E, 6E) 8-bromo-3,7-dimethylocta-2,6-dienoate 2 have been used as substrates and ...
Synthesis and characterization of s-cis-bis(ethylenediamine-N,N′-diacetato)-μ-O,O′-glycinato-μ- hydroxo-dichromium(III)monohydrate
(Journal of the Serbian Chemical Society, 1997)
The reaction between s-cis-diaqua-(ethylenediamine-N,N′-diacetato)-chromium(III) nitrate and glycine (mole ratio 1:1, pH = 6, 80 °C, 2 h) results in the formation of two nonelectrolytic compounds. One of them was identified ...
Study of photochemical reactions of coniferyl alcohol .1. Mechanism and intermediate products of UV radiation-induced polymerization of coniferyl alcohol
(Amer Soc Photobiology, Augusta, 1997)
Ultraviolet light-induced photochemical transformations of coniferyl alcohol have been studied, using spectrophotometric and H-1 NMR approaches. It was shown earlier that coniferyl alcohol can be polymerized not only ...
