In combination with hydroquinone, selective aerobic oxidation of a primary alcohol to an aldehyde, in the presence of a secondary alcohol, can be achieved: Tetrahedron Lett., 39, 5557 (1998).

Alkylated arenes can be oxidized to ketones by tert-butyl hydroperoxide, catalyzed by the complex: J. Org. Chem., 65, 9186 (2000).
