The odd-numbered carbon clusters C[sub 119], C[sub 129], and C[sub 139] have been observed in the mass spectra of toluene extracts of fullerene soots and of the products of ozone-fullerene reactions. Specifically, ozone-C[sub 60] reactions yield C[sub 119], ozone-C[sub 70] reactions yield C[sub 139], and ozone-(C[sub 60]/C[sub 70]) reactions produce C[sub 119], C[sub 129], and C[sub 139]. These unexpected species correspond to dimers of C[sub 60], C[sub 60]/C[sub 70], and C[sub 70], respectively, less one carbon atom, and are stable gas-phase ions with behavior similar to that of fullerenes. The results suggest a new route to functionalization and derivatization of fullerenes through controlled ozone-catalyzed cage-opening reactions. 11 refs., 3 figs.
