Abstract

The formation and spectroscopic characterization of a superoxido cobalt(III) and a peroxido dicobalt(III) species formed in the temperature dependent reversible reaction of a cobalt(II) precursor with O₂ is described. The electronic nature of each species is explored in their reactivity with organic substrates.
