diadamantylidene 6 in the presence of fullerene C60,
nearly half of the catalyst was converted to C60O and
C60O2 oxides. In our experiments the C60 conjugates
were recovered unchanged from the reaction mixture,
which enabled their reuse. To this end, upon com-
pletion of the reaction these substances were isolated
by column chromatography using 3 : 1 petroleum ether–
ethyl acetate as eluent.

Thus, with triphenylphosphine taken as an example
we demonstrated the capability of fullerene C60 and of
its readily soluble derivatives to sensitize an oxidation
process under mild conditions of atmospheric oxygen.
The time of the process was significantly reduced
through the use of a xenon lamp.

General procedure for the oxidation of triphenyl-
phosphine and diadamantylidene with atmospheric
oxygen in the presence of fullerene C60 or of its
conjugates. A mixture of 1.4 mmol of triphenyl-
phosphine (or diadamantylidene) with 0.14 mmol of
fullerene C60 or of its conjugates 1–5 in 35 mL of
toluene was stirred in an open glass vial under daylight
(or under illumination with a xenon lamp placed at a
distance of 20 cm from the reactor) until triphenyl-
phosphine completely disappeared. The progress of the
reaction was monitored by thin layer chromatography.
Diadamantylidene epoxide was isolated by column
chromatography using CH2Cl2 as eluent.

The reaction was run in an FO-1 vial made of NS-3
medical glass. A ClearLight 5000K xenon lamp with a
35 W ignition block was used in the experiments.
The NMR spectra were recorded on a Bruker-AM
500 spectrometer operating at 125.76 MHz (13C), with
tetramethylsilane as internal reference. Elemental
analysis was performed using a EURO EA-3000 CHN
instrument. The melting point was determined on a
Böetius micro-heating apparatus.
