资源简介：
A series of cerium complexes containing
a 2,2′-methylenebis(6-tert-butyl-4-methylphenolate)
(MBP2–) ligand framework is described. Electrochemical
studies of the compound [Li(THF)2Ce(MBP)2(THF)2] (1) reveal that the metal based oxidation wave
occurs at −0.93 V vs Fc/Fc+. This potential demonstrates
significant stabilization of the cerium(IV) ion in the MBP2– framework with a shift of ∼2.25 V from the typically reported
value for the cerium(III/IV) couple of E°′
= +1.30 V vs Fc/Fc+ for Ce(ClO4)3 in HClO4 solutions. Compound 1 undergoes
oxidation to form stable cerium(IV) species in the presence of a variety
of common oxidants. The coordination of the redox-active ligands 2,2′-bipyridine
and benzophenone to 1 result in complexes in which no
apparent metal-to-ligand charge transfer occurs and the cerium ion
remains in the +3 oxidation state.
