title: Synthesis of fullerene-fused lactones and fullerenyl esters: radical reaction of [60]fullerene with carboxylic acids promoted by manganese(III) acetate and lead(IV) acetate.
abstract: The manganese(III) acetate-mediated radical reaction of [60]fullerene with carboxylic acids in the presence of 4-(dimethylamino)pyridine exclusively afforded the [60]fullerene-fused lactones. Interestingly, the lead(IV) acetate-promoted radical reaction of [60]fullerene with the same carboxylic acids selectively gave another type of fullerene products, i.e., fullerenyl esters. Possible mechanisms for the formation of fullerene products are proposed.
