Redox and Photochemical Reactivity of Cerium(IV) Carbonate and Carboxylate Complexes Supported by a Tripodal Oxygen Ligand.

ABSTRACT: The protonolysis and redox reactivity of a Ce(IV) carbonate complex supported by the Kläui tripodal ligand [(η⁵-C₅H₅)Co{P(O)(OEt)₂}₃]^- (L_OEt^-) have been studied. Whereas treatment of [Ce(L_OEt)₂(CO₃)] (1) with RCO₂H afforded [Ce(L_OEt)₂(RCO₂)₂] (R = Me (2), Ph (3), 2-NO₂C₆H₃ (4)), the reaction of 1 with PhCH₂CO₂H resulted in formation of a mixture of Ce(IV) (5) and Ce(III) (6) carboxylate species. In benzene in the dark, 5 was slowly converted into 6 via Ce(IV)-O(carboxylate) homolysis. Recrystal
