Abstract
In the presence of F-, OH-, Cl-, electrochemical redox of (OEP)Mg(II) [2,3, 7,8,12,13,17,18 octaethyl-21H, 23H-porphine magnesium (II)] are investigat ed in DCE/0.1 mol/L solution by cyclic voltammetry and spectroelectrochemis try, In the presence of anions, anions are axially coordinated to (OEP)Mg(I I) generate (OEP)Mg(II)Y, the E-1/2 of (OEP)MS(II)Y oxidation are negativel y shifted. A chemical reaction following the second oxidation step is obser ved, the E-1/2 of the reaction product is obtained. Mechanism of (OEP)Mg(II ) in the halogen and OH- anions titration process has been proposed.
