CoSALEN as a new catalyst for oxidation of fullerene C₆₀

Abstract

The effect of CoSALEN on anti-oxidative properties of fullerene C₆₀ in the presence of O₂ in cumene was investigated. A comparison was made between the role of the CoSALEN as a catalyst in the C₆₀ oxidation and oxidation in the presence of an initiator, i.e., AIBN. A mechanism is proposed for the catalytic role of CoSALEN in oxidation of C₆₀. Oxidation of octadecylaminofullerene C₆₀ at the same conditions reveals that oxidation could be a result of hydroperoxidation of the unreacted sites of C₆₀. We conclude that C₆₀ as well as its amino-derivatives enhance the efficiency of CoSALEN in the oxidation of cumene due to their radical scavenging property of their unreacted double-bond sites.
