摘要：

Electrochemical behaviours of UO2(P-diketonate)(2)DMF, UO2(troP)(2)DMF and UO2(sap)(DMF)(2), (DMF, N,N-dimethylformamide; beta-diketonate, thenoyltrifluoroacetonate(ttfa); benzoyltrifluoroacetonate(btfa) and dibenzoylmethanate(dbm); trop, tropolonate and sap, 2-salicylidenaminophenolate) complexes in DMF solution containing tetrabutylammonium perchlorate as a supporting electrolyte have been investigated by cyclic voltammetry. These uranyl(VI) complexes were found to be quasi-reversibly reduced to U(V) species. The formal redox potentials (E-0, versus ferrocene/ferrocenium) for U(VI)/U(V) Couples were determined to be - 1.176 V for UO2(ttfa)(2)DMF, - 1.183 V for UO2(btfa)(2)DMF, - 1.461 V for UO2(dbm)(2)DMF, - 1.456 V for UO2(trop)(2)DMF and - 1.585 V for UO2(sap)(DMF)(2) Complex.
