Substituent efects on the carbon-13 chemical shifts in α-phenylpyridylacrylic acids
(Elsevier Science Publishers B.V., 1992)
The 13C N.M.R. spectra of some substituted α-phenylpyridylacrylic acids, α-phenyl, α-(3-pyrydyl) and α-(3-pyrydyl-N-oxide) cinnamic acids were determined in deuterated dimethyl sulfoxide (d6-DMSO). It has been shown that ...
Synthesis, characterization, antimicrobial activity and DFT study of some novel Schiff bases
(Elsevier, 2021)
Two new Schiff bases derived from L-cysteine and substituted benzaldehyde were synthesized: the compound 1 [2-((2-chlorobenzylidene) amino)-3-mercaptopropanoic acid] and the compound 2 [3-mercapto-2-((2-methoxybenzylidene) ...
The solvent effect on the conformational equilibrium of 1,3-dichloro-5-methylcylclohexane
(Elsevier, 1985)
The conformational equilibrium has been measured for r-1,c-3-dichloro-t-5-methylcyclohexane(2) in six solvents from the 500 MHz and 400 MHz 1H NMR spectra. The room-temperature and low-temperature C1H couplings are used ...
The predicted infrared spectrum of the hypermetallic molecule CaOCa in its lowest two electronic states (X)over-tilde(1)Sigma(+)(g); and (a)over-tilde(3)Sigma(+)(u)
(Elsevier, 2012)
This study of CaOCa is our third paper in a series on Group 2 alkaline-earth M2O hypermetallic oxides. As with our previous calculations for BeOBe and MgOMg, the ab initio calculations we report here show that CaOCa has a ...
Structure-property relationship of 3-(4-substituted benzyl)-1,3-diazaspiro[4.4]nonane-2,4-diones as new potentional anticonvulsant agents. An experimental and theoretical study
(Elsevier, 2017)
The structure-property relationship of newly synthesized 3-(4-substituted benzyl)-1,3-diazaspiro [4.4] nonane-2,4-diones was studied by experimental and calculated methods. The prepared compounds were characterized by ...
Synthesis, antimicrobial activity and quantum chemical investigation of novel succinimide derivatives
(Elsevier, 2019)
In the present study, twelve new 1-aryl-3-ethyl-3-methylpyrrolidine-2,5-diones were synthesized and their structures were characterized by FT-IR, 1H NMR, 13C NMR spectroscopy and elemental analysis. In the final step of ...
Experimental and theoretical study on the structure-property relationship of novel 1-aryl-3-methylsuccinimides
(Elsevier, 2017)
A series of ten 1-aryl-3-methylsuccinimides was synthesized and their solvatochromic properties were studied in a set of fifteen binary solvent mixtures. The solute-solvent interactions were analyzed on the basis of the ...
Preparation, characterisation and study of in vitro biologically active azamacrocyclic Cu(II) dicarboxylate complexes
(Elsevier, 2013)
New cationic Cu(II) complexes with N, N', N '', N'''-tetrakis(2-pyridylmethyl)-1,4,8,11-tetraazacyclotetradecane (tpmc) and aliphatic dicarboxylic acids: pentanedioic (glutaric acid = glutH(2)), hexanedioic acid (adipic ...
Conformational analysis of edta-type rhodium(III) complexes with mixed five- and six-membered chelate rings. Structural analysis of conformational flexibility in rhodium(III) complexes containing 1,3-propanediamine-N,N′-diacetate-N,N′-di-3-propionate ligand
(Journal of Molecular Structure, 2006)
Conformational analysis of the three possible geometrical isomers: trans(O5), trans(O5O6) and trans(O6) of the sexidentate [Rh(1,3-pddadp)]- complex, and of the 10 possible isomers: four cis-equatorial, four cis-polar and ...
