Transition Metal Salt-Mediated Radical Reactions of [60]Fullerene

Various transition metal salts have been employed to the radical reactions of [60]fullerene (C60). The present review article covers the reactions of C60 with active methylene compounds, methyl ketones, β-enamino carbonyl compounds, carboxylic acid derivatives, and diallylamines in the presence of Mn(OAc)3·2H2O affording the singly bonded fullerene dimers, 1,4-adducts and 1,16-adduct of C60, C60-fused dihydrofurans, methanofullerenes, C60-fused pyrrolines, C60-fused lactones, fullerenyl ester derivatives, and C60-fused pyrrolidines as well as the transformation of ArC60-H into ArC60-OAc by Mn(OAc)3·2H2O. Radical reactions of C60 promoted by other transition metal salts including copper(II), lead(IV), iron(III), ruthenium(II/III), tungsten(VI), cerium(IV) salts are also described.
