    • ® DAP beads (0.2-0.5 mm), namely a silicon polymer). On the other hand, the present catalyst prepared by linking of fullerene to amino-functionalized silica gels (40-60 μm), is able to be carried out in solvent-free photooxygenation by efficient utilization of silica gel part as a 'solid-phase reaction field'.

    • Fullerene (100 mg) and 3-aminopropyl-functionalized silica gel or 3-(diethylenetriamino)propyl-functionalized silica gel (500 mg, Aldrich Co. Ltd.) were reacted in toluene (50 mL) at 60°C for 8 h under Ar atmosphere. The resulting compound was filtrated, and then washed by hot toluene until the color of the toluene passing through the filter was clear to give the corresponding catalyst.

    • 3, and then the catalyst (100 mg) was added to the solution. The mixture was similarly irradiated in a quartz cell with visible-light (λ >380 nm), where air was passed through it continuously by using a bubbling system. After the reaction, the reaction mixture was filtrated and the catalyst was washed well with chloroform or ethyl acetate. Then, the resulting filtrate was concentrated under reduced pressure to afford the corresponding product.
