Oxidation and catalytic properties of a binuclear copper(I) complex with a meta-xylyl spacer ligand (2003)The oxidation product of the binuclear copper (I) complex Cu2L(CIO4)2 (L = N,N′-bis-(6-methyl-2-pyridil) (2′-pyridyl)methyl m-xylylidene imine) has been isolated and structurally characterised. In the cupric species, ...

(ELECTROCHEMICAL SOC INC, 2008)Electrochemical oxidation of 4-(3-indolyl)- and 4-(5-indolyl)-1,4-dihydropyridines (DHPs) in aprotic and protic media is reported. Also, the reactivity of compounds toward alkylperoxyl radicals 2,2'-azobis-(2-amidinopropane) ...
-
(PERGAMON-ELSEVIER SCIENCE, 2007-06-15)This work reports the electrochemical oxidation of three newly synthesized C4-hydroxyphenyl-substituted 1,4-dihydropyridine derivatives in dimethylsulfoxide. The reactivity of the compounds with ABAP-derived alkylperoxyl ...
-
(KLUWER ACADEMIC/PLENUM PUBL, 2004-03)The final pyridine derivatives were separated and identified by gas chromatography/ mass spectrometry (GC-MS). The intermediates, anion dihydropyridine and the HO2./HO2- species, were observed from voltammetric studies and ...
