摘要：

Tris(acetylacetonato)cobalt(III), tris(benzoylacetonato)cobalt(III), and tris(dibenzoylmethanato)cobalt(III) have been photolyzed in different organic solvents. The complexed Co(III) ion is reduced photochemically to Co(II) with simultaneous oxidative fragmentation of one β-ketoenolate group. The reaction was partly reversible in the presence of oxygen. The quantum yields were found to be wavelength dependent and ranged from around 10-3 for excitation in the first d-d band to 0.6 in the ultraviolet region. A reaction mechanism consistent with the identified photoproducts is proposed. © 1969, American Chemical Society. All rights reserved.
