Electrochemical approach to the radical anion formation from 2′-hydroxy chalcone derivatives
(2006)
Three 2′-hydroxy chalcone derivatives were electrochemically reduced to the radical anion by a reversible one-electron transfer followed by a chemical dimerization reaction. Under suitable conditions of the medium, the ...
Reactivity of 2-aryl-1,3-dithiane anions towards neopentyl, neophyl and phenyl iodides. New evidence for an SRN1 mechanism
(John Wiley & Sons Ltd, 2011-12)
The reactions of 2-(4-Z-phenyl)-1,3-dithiane anions (Z=H, OMe, Cl, CN) with neopentyl, neophyl and phenyl iodides were studied in DMSO, taking into consideration the effect of the Z substituent on the dithiane anions ...
BEHAVIOR OF THE ANION-RADICALS ELECTROCHEMICALLY GENERATED IN THE REDUCTION OF NOSYL AMIDES
(Elsevier B.V., 1994-01-01)
The behaviour of nitrobenzenesulfonamide anion radicals generated from the electrochemical reduction of aliphatic and aromatic amines protected by nitrobenzenesulfonyl (nosyl) groups in N,N-' dimethylformamide has been ...
BEHAVIOR OF THE ANION-RADICALS ELECTROCHEMICALLY GENERATED IN THE REDUCTION OF NOSYL AMIDES
(Elsevier B.V., 1994-01-01)
The behaviour of nitrobenzenesulfonamide anion radicals generated from the electrochemical reduction of aliphatic and aromatic amines protected by nitrobenzenesulfonyl (nosyl) groups in N,N-' dimethylformamide has been ...
Reactivity of the nitro radical anion from nisoldipine with N-acetylcysteine: EPR spectroscopic and electrochemical evidence
(Sociedad Chilena de Química, 1998)
This paper reports the scavenging of the nitro radical anion of nisoldipine by N-acetylcysteine assessed by cyclic volatammetry (CV) and EPR spectroscopic techniques. Studies by CV on the reactivity of the radical were ...
Nitrosobenzene: electrochemical, UV-visible and EPR spectroscopic studies on the nitrosobenzene free radical generation and its interaction with glutathione
(PERGAMON-ELSEVIER SCIENCE, 2000)
This paper reports both the electrochemical characterization and the reactivity of the nitroso radical anion from nitrosobenzene with glutathione. The reduction of nitrosobenzene to the corresponding nitroso radical anion ...
Role of peroxynitrite in macrophage microbicidal mechanisms in vivo revealed by protein nitration and hydroxylation
(Pergamon-elsevier Science LtdOxfordInglaterra, 2001)
Electrochemistry and reactivity against superoxide anion radicals of hydroxycoumarins and its derivatives
(Electrochemical Soc Inc, 2020)
The present studies reveal superoxide radical anion reactivity against synthesized coumarins. Free radicals play an important role in many diseases and they have a protective function also. Therefore, we must keep a balance ...
Formation of radical anions by electrochemical reduction of nitroimidazoles in aprotic solvents and mixed solvent
(Marcel Dekker Inc.Taylor & Francis, 1996)
The EPR spectra of radicals obtained by electrohytical reduction of 2-nitroimidazole and 4-nitroimidazole were measured in mixed solvents. The behavior of the nitrogen coupling constants with the solvent composition is ...
Nitroradical anion formation from some iodo-substituted nitroimidazoles
(WILEY-V C H VERLAG GMBH, 2005-09)
The electrochemical behavior of iodo nitroimidazole derivatives such as 1-methyl-4-iodo-5-nitroimidazole (M-I-NIm) and 1-methyl-2,4-diiodo-5-nitroimidazole (M-I-2-NIm) and the parent compound 1-methyl-5-nitroimidazole ...
