A C60 derivative bearing an organofluorine tail through the dimethylsilyl moiety (1) was proved to be an efficient photosensitizer in C6F6. Photooxygenation of olefins or dienes was accomplished by catalysis of 1 (0.5 - 1.5 mo1%) at room temperature under an oxygen atmosphere.
EFFECTS OF HETEROATOM SUBSTITUENTS ON THE PROPERTIES OF 1,2-DIOXETANES

Nitrogen and sulfur-substituted dioxetanes exhibit dramatically lower activation energies for decomposition compared to the corresponding oxygen-bearing dioxetane.A mechanism involving intramolecular electron-transfer processes is proposed for the cleavage of these unstable dioxetanes.

The first members of dioxetanocrown ethers 3 and 4 were prepared in methylene blue-sensitized,photooxygenations of 9- and 18-membered stilbecrown ethers 1 and 2, and the activation paramethers for the thermolyses of 3 and 4 were obtained.Thermal decomposition of the bis-dioxetano-18-crown-6 4 was decelerated,or accelerated in the presence of alkali metal salts depending upon the nucleophilicity of the counter anion.
