The rate constant for the addition of benzyl radicals to C[sub 60] in toluene is determined by time-resolved ESR spectroscopy as k[sub 298] = (1.4 [+-] 0.2) [times] 10[sup 7] M[sup [minus]1] s[sup [minus]1] with log A/M[sup [minus]1] s[sup [minus]1] = 9.5 [+-] 0.3 and E[sub a] = 13.5 [+-] 0.2 kJ/mol. This agrees with a previous correlation between log k/M[sup [minus]1] s[sup [minus]1] and electron affinities for benzyl addition to alkenes and shows that the addition of C[sub 60] is strongly facilitated by charge transfer in the transition state. 13 refs., 2 figs.
