Oxygenation of Tetrahydrofurans with Combined Use of Molecular Oxygen and α-Diketone Catalyzed by Cobalt(III) Complex

Article abstract of DOI:10.1246/cl.1993.1513

In the presence of catalytic amount of cobalt(III) complex such as tris(acetylacetonato)cobalt(III), tetrahydrofurans are oxygenated into the corresponding γ-butyrolactones under mild conditions on treatment with an atmospheric pressure of molecular oxygen and α-diketones having hydrogen atom next to the carbonyl carbon.
