AbstractCo-II(por) (por = porphyrinato dianion) reacted selectively with isopropyl ketones at the carbon (CO)-carbon (a alpha bond at room temperature to give high yields of Co-III(por) aryls and the corresponding oxidized carbonyl compounds in up to 89% yields. Co-III(por)OH is proposed to be the C-C bond activation (CCA) intermediate. The stoichiometric reaction is further developed into the photocatalytic CCA using both UV and visible light sources (lambda 405 nm). Under ambient conditions, the photocatalytic C-C oxidation of 2,6-dimethylcyclohexanone gives 2-heptanone in up to 24 turnovers in the presence of isopropyl alcohol as the H atom donor and H2O as the oxidant. Various isopropyl ketones successfully undergo photocatalysis.
