The rate constant for the addition of benzyl radicals to C60 in toluene is determined by time-resolved ESR spectroscopy as k298 = (1.4 +/- 0.2) X 10(7) M-1 s-1 with log A/M-1 s-1 = 9.5 +/- 0.3 and E(a) = 13.5 +/- 0.2 kJ/mol. This agrees with a previous correlation between log k/M-1 s-1 and electron affinities for benzyl addition to alkenes and shows that the addition Of C60 is strongly facilitated by charge transfer in the transition state.
