Systems involving direct oxidation by metal ions 

Direct oxidation, similarly to the first step of cyclohexane oxidation above, is a useful reaction for selective oxidation of simple alkanes relatively high concentrations of cobalt(II) acetate are 

In the absence of oxygen, at 80 °C, cobalt(III) acetate oxidizes cyclohexane to cyclohexyl acetate and 2-acetoxycyclohexanone as main products [35]. The lack of a deuterium kinetic isotope effect in this reaction is consistent with rate-determining electron transfer to 

The relative rates of oxidation of various cycloalkanes by cobalt(III) acetate in acetic acid have been reported [36-38]. The complex formation between the alkane and Co(III) is strongly influenced by steric factors. 

The oxidation of cyclohexane by cobalt(III) acetate is accelerated by bromide ions [39]. This effect is probably due to chain transfer by bromine atoms.
