Abstract
Reactions of copper(II) complex with tetrabenzo- [b,f,j,n] [1,3,9,13]tetraazacyclohexadecine (TAAB) as a Lewis acid have been studied. Coordination of solvent molecules and stabilization of the copper(II) oxidation state according to solvent donor properties has been confirmed. The product of hydroxyl ion nucleophilic addition has been isolated and characterized. Differences in electrochemical as well as chemical reduction and reoxidation of the complex in acidic and basic medium have been investigated and the reaction mechanism is discussed.
