This study describes the effects of the substituents on electrochemical behavior and antioxidant activity of the three tetradentate Schiff bases, containing ethane-1,2- diamine, propane-1,3- diamine and butan-1,4- diamine as the amine part and salicylaldehyde, and corresponding Cd(II) complexes. Cyclic voltammograms of these compounds were recorded in dimethylsulfoxide and 0.1 M sodium perchlor...

new hetero-binuclear hg-cu schiff base complexes were prepared by reaction of 2,2'-[1,1'-(2,2-‎dimethylpropane-1,3-diyldinitrilo)-diethyldyne]diphenolato}copper(ii) (cul1) and 6,6'-x-2,2'-[(2,2-‎dimethylpropane-1,3-diyl)bis(nitrilomethanylylidene)]diphenolato copper(ii) [(x = ethoxy (cul2) and ‎methoxy (cul3)], with hgcl2 to give [cu(l1)hgcl2] (1), [cu(l2)hgcl2] (2), and [cu...

the vo(iv) complexes of tridentate ono schiff base ligands derived from 2- aminobenzoicacid and salicylaldehyde derivatives were synthesized and characterized by ir, uv–vis and elemental analysis. electrochemical properties of the vanadyl complexes were investigated by cyclic voltammetry. a good linear correlation was observed between the oxidation potentials and the electron-withdrawing charac...

A novel Schiff base was synthesized by the reaction of piperonal and anthranilic acid, which was further utilized in the synthesis of five novel complexes by reaction with different metal salts ultrasonically. Time for the reaction was greatly reduced through ultrasound irradiations and the yield of reactions was also high as compared to the conventional methods using reflux conditions. The...
