Photochemical reaction of the open-cage fullerene derivative with singlet oxygen
Photochemical reaction of open-cage fullerene 1 with singlet oxygen gave oxidation product 3, which was shown to have an enol and a carbonyl groups on the 12-membered-ring orifice on the fullerene cage by spectroscopic method and density functional calculations.
