Electrochemical benzylation of [60]fullerene-fused lactones with different motifs unexpectedly affords three types of ring-opened benzylated adducts under different conditions. Both [60]fullerene-fused δ- and γ-lactones can be benzylated to generate ring-opened mono- and bis-benzylated adducts in good yields. In addition, representative fullerene products have been applied as efficient electron-transport

Reactions of [60]fullerene-fused lactones with methylmagnesium bromide and diisobutylaluminum hydride afforded rare fullerene hemiketals and hemiacetals, which were dehydrated by p-toluenesulfonic acid monohydrate or polyphosphonic acid to the corresponding [60]fullerene-fused dihydrofurans. Thus obtained alkyl-substituted and especially unsubstituted [60]fullerene-fused dihydrofurans are difficult to prepare by other methods. The unsubstituted [60]fullerene-fused lactone could react with aliphatic amines to give fullerols.

[reaction: see text] [60]Fullerene-fused lactones were prepared by the manganese(III) acetate-mediated reactions of [60]fullerene with carboxylic acids, carboxylic anhydrides, or malonic acids. Novel reductive ring opening of the lactones with Grignard reagents was observed.

Reaction of C60 with diethylaminopropyne leads to cyclobutene adduct 1, which upon acid hydrolysis provides a facile synthetic route to fullerene adduct 2. Subsequent oxidative cyclization involving activated carbon yields the novel fullerene lactone 3.
