SYNTHESIS OF N-MORPHOLINE OR N,N-DIETHYL, N'-MONOSUBSTITUTED BENZOYL THIOUREA COPPER-COMPLEXES - CHARACTERIZATION AND ELECTROCHEMICAL INVESTIGATIONS

A series of N-morpholine or N,N-diethyl, N'-substituted benzoyl thiour eas (R = Cl, Br, OMe or NO2 in ortho, meta or para position) have been synthesized by condensation of morpholine or diethylamine with substi tuted benzoyl isothiocyanates. All CuL2 complexes have been characteri zed. Cyclic voltammetry has shown that the irreversible process copper (II)/copper(I) redox systems are influenced slightly by the substituti on, whereas the quasi-reversible copper(III)/copper(II) redox systems are not.
