The Co-catalyzed hydroalkylation of C 60 with reactive alkyl bromides 1 (RBr) in the presence of Mn reductant and H 2O at ambient temperature gave the monoalkylated C 60 (2) in good to high yields. The use of CoLn/Mn/H 2O under Ar atmosphere is crucial for the success of the present transformation. The reaction most probably proceeds through the Co(0 or I) complex-promoted generation of a radical (R ) followed by addition to C 60. This hydroalkylation method was applied to the synthesis of zinc porphyrin attached C 60 (2l), dendrimer attached C 60 (2m), and fullerene dimer (2n), which were not easily available through the previously known methods.
