Abstract

Die aus den Betainen (III) mit den Elektrophilen (VI), (VIII).

Structure, photophysics, electrochemistry, DFT calculation, and in-vitro antioxidant activity of coumarin Schiff base complexes of Group 6 metal carbonyls

“…Present series of molecules [M (CO) 4 (L)] may be included in the CORM family. 4 (L)] has been confirmed by single crystal X-ray diffraction study. The ligand belongs to π-acidic diimine family and stabilizes M(0) oxidation state.…”

“…N(12)-Cr(1)-N(9) is 0.6°lower than the experimental data. DFT calculations of the ligand and [Cr(CO) 4 Table S3). …”

Cytotoxic effect, differentiation, inhibition of growth and theoretical calculations of an N,N-donor ligands and its platinum(II), palladium(II) and copper(II) complexes

“…Chromone (benzo-c-pyrone) derivatives constitute another class of biologically important compounds, which display a wide range of biologically relevant properties including anticonvulsant [4], antimicrobial [5,6] and antitumor activities [7][8][9]. The reaction with primary amines on the chromone system, leading to the opening of the c-pyrone ring, is followed by spontaneous cyclisation of the intermediary enamino ketones into coumarin derivatives.…”

Electrooxidation of Iodide in the Presence of 4-Hydroxycoumarin: Application to a Simple Coulometric Titration of 4-Hydroxycoumarin

“…4-Hydroxycoumarin with anticoagulant activity 1 is widely used to prepare pharmaceutical and some of biologically important compounds, such as warfarin 2 diazepins, 3 pyranocoumarins and coumarinopyrano pyrimidines, 4 antiplatelet compounds, 5 benzopyranopyrano quinolines 6 and fercoprolones, 7 analogues of novobicin 8 and coumestans. 9,10 It has also been identified as an intermediate in many processes.…”
