Tetravalent cerium complexes containing oxygen donor ligands
Project Description

Cerium (Ce) is the only rare earth metal that forms stable tetravalent complexes in solution. Owing to the facile Ce(IV/III) redox couple, cerium-containing compounds and materials have been widely used in organic oxidations and heterogeneous catalysis. Despite their diverse applications, the reaction chemistry of oxidizing Ce(IV) compounds has not been well explored and the mechanism by which Ce(IV) compounds oxidize organic substrates is not well understood. In this project, Ce(IV) compounds with oxygen-donor ligands such as oxo and alkoxides will be synthesized, and their reactivity toward organic substrates will be studied. The mechanism of the oxidation of X-H (X = C, N, O) bonds by Ce(IV) compounds will be elucidated.
