Magnetic criteria of aromaticity in a benzene cation and anion: how does the Jahn-Teller effect influence the aromaticity?
(Oxford : Pergamon-Elsevier Science Ltd, 2012)
The aromatic/antiaromatic behavior of the Jahn-Teller UT) active benzene cation and anion has been investigated using Density Functional Theory (DFT) calculations of Nuclear Independent Chemical Shifts (NICS) and magnetic ...
Debromination of endo-(+)-3-Bromocamphor with Primary Amines
(Soc Brasileira Quimica, Sao Paulo, 2013)
Reductive debromination of endo-(+)-3-bromocamphor with different primary amines followed by imine formation was investigated. This reaction requires simple experimental procedure without any organic solvent, metal or ...
Antioxidant properties of selected 4-phenyl hydroxycoumarins: Integrated in vitro and computational studies
(Elsevier Ireland Ltd, Clare, 2014)
A study on the structure-activity relationship of three hydroxy 4-phenyl coumarins, carried out by employing a series of different chemical cell-free tests is presented. Different assays involving one redox reaction with ...

(Elsevier, 2008)
The novel N,N-type bidentate ligand precursors, diethyl, dipropyl esters of ethylenediamine-N,N′-diacetic acid dihydrochloride (HOOCCH2NHCH2CH2NHCH2COOH • 2HCl, H2edda • 2HCl), and the corresponding tetrachloroplatinum(IV) ...
Syntheses, characterization and antimicrobial activity of the first complexes of Zn(II), Cd(II) and Co(II) with N-benzyloxycarbonylglycine. X-ray crystal structure of the polymeric Cd(II) complex
(Elsevier S.A., 2008)
For the first time, complexes of Zn(II), Cd(II) and Co(II) (1-3) with N-benzyloxycarbonylglycine have been synthesized and characterized. The complexes adopt tetrahedral, pentagonal-bipyramidal and octahedral geometry, ...
Spectroscopic and quantum chemical investigations of substituent effects on the azo-hydrazone tautomerism and acid-base properties of arylazo pyridone dyes
(Oxford : Pergamon-Elsevier Science Ltd, 2014)
A series of 5-(4-substituted arylazo)-6-hydroxy-4-methyl-3-cyano-2-pyridone dyes was synthesized and the structure of the dyes was confirmed by UV-Vis, FT-IR, H-1 NMR and C-13 NMR spectroscopic techniques. The azo-hydrazone ...
