Methoxylation of the singly bonded 1,4–1′,4′-BnC<sub>60sub>–C<sub>60sub>Bn dimer afforded 1,4-OMe(Bn)C<sub>60sub>, a 1,4-C<sub>60sub> adduct with sterically less demanding addends, as the major adduct. The situation was different from that of direct functionalization of C<sub>60sub>, where 1,2-OMe(Bn)C<sub>60sub> was obtained as the major product. The reaction was studied with in situ vis-NIR spectroscopy and computational calculations to obtain a better understanding of this unusual regioselectivity. The stability difference between 1,2- and 1,4-OMe(Bn)C<sub>60sub> was studied.
