Controlling Pd-Catalyzed N-Arylation and Dimroth Rearrangement in the Synthesis of N,1-Diaryl-1H-tetrazol-5-amines
(American Chemical Society (ACS), 2021)
The Pd-catalyzed N-arylation method for the synthesis of eighteen N,1-diaryl-1H-tetrazol-5-amine derivatives is reported. By running the reactions at 35 °C, compounds were isolated as single isomers since the undesired ...
Synthesis, X-ray structures and magnetic properties of Ni(II) complexes of heteroaromatic hydrazone
(Elsevier, 2020)
Two binuclear double end-on azido bridged Ni(II) complexes, [Ni2L2(μ-1,1-N3)2(N3)2]⋅2H2O (1a), and [Ni2L2(μ-1,1-N3)2(N3)2]⋅4H2O (1b) having the same inner sphere, where L=((E)-N,N,N-trimethyl-2-oxo-2-(2-(1-(thiazol-2-yl) ...
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 ...
Platinum(IV) complexes with ethylenediamine-N,N0-diacetate diester (R2edda) ligands: Synthesis, characterization and in vitro antitumoral activity
(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) ...
A novel approach in revealing mechanisms and particular step predictors of pH dependent tartrazine catalytic degradation in presence of Oxone®
(Elsevier, 2021)
The degradation of tartrazine in the presence of cobalt activated Oxone® (potassium peroxymonosulfate) was investigated at different initial pH values. Aluminum pillared clay had the role of a support for catalytically ...
What Is the Nature of Interactions of BF4–, NO3–, and ClO4– to Cu(II) Complexes with Girard’s T Hydrazine? When Can Binuclear Complexes Be Formed?
(American Chemical Society (ACS), 2019)
In solid-state coordination chemistry, the coordination number of a metal center is not always unambiguously determined, as sometimes from the geometrical parameters it is not clear if ligands are directly bound to the ...
What is the nature of bonding in [Fe(CO)3(NO)]− and [Fe(CO)4]2−?
(Springer Nature, 2020)
To shed new light on the electronic structure of [Fe(CO)3(NO)]¯ complex ion, DFT-based analysis of the nature of chemical bonding has been performed. For this purpose, the extended transition state energy decomposition ...
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 ...
