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) ...
Effect of substituents on the 13 C chemical shifts of the azomethine carbon atom of N-(phenyl substituted) pyridine-4-aldimines
(Elsevier, 1999)
13 C chemical shifts of the azomethine carbon atom for N-(substituted phenyl)pyridine-4-aldimines, 4-Py-CH=N-C 6 H 4 -X, X having a wide range of substituent effects, have been determined in CDCl 3 solution. Exceptionally ...
Configurations in unsymmetrically N-methyl-N-substituted 2-phenylacetamides
(Elsevier, 1986)
The syntheses of a various N-methyl-N-substituted 2-phenylacetamides of the general formula PhCH 2 CON(CH 3 )R, wherein, R is ethyl, n-propyl, isopropyl and t-butyl group, were performed. The 1 H n.m.r. spectra of these ...
Binuclear biologically active Co(II) complexes with octazamacrocycle and aliphatic dicarboxylates
(Elsevier, 2012)
Four new cationic Co(II) complexes with N,N',N '',N'''-tetrakis (2-pyridylmethyl)-1,4,8,11-tetraazacyclotetradecane (tpmc) and dianion of one the aliphatic dicarboxylic acids: butanedioic acid (succinic) acid = succH(2), ...
Novel derivatives of aroylacrylic acid phenylamides as inducers of apoptosis through the ROS-mediated pathway in several cancer cell lines
(Elsevier, 2022)
In the present work, the α, β-double bond of the aroylacrylic acid phenylamides was suitably modified to optimize the toxicity–antiproliferative activity ratio of the resulting compounds 1 –5 . The phenylamides were modified ...
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 ...
Preparation, characterization and X-ray analysis of [Co2(Cl)2tpmc](BF4)2. Comparative structural analysis with the complexes having analogous geometries and ligands
(Elsevier, 2007)
A novel binuclear Co(II) complex, [Co2(Cl)2tpmc](BF4)2 (tpmc = N,N′,N″,N‴-tetrakis(2-pyridylmethyl)-1,4,8,11-tetraaz acyclotetradecane), was prepared and structurally characterized by X-ray diffraction analysis at low ...
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 ...
