THERMOCHEMISTRY OF THE GAS-PHASE REACTIONS OF FLUOROFULLERENE ANIONS

The ion-molecule equilibrium method has been applied to studies of the gas phase fluorine exchange reactions between fullerene anions and me tal fluoride anions. This has yielded the first quantitative determina tion of the absolute values of Gibbs energies for addition of fluorine to the anions of higher fullerenes C-70+2n(-) (n = 0, 1, ..., 7) and sequential fluorine addition in the series C60Fn- (n = 0, 1, 2) Estima tes for C-F bond dissociation energies of C60F2 and C70F2 and electron affinities of monofluorinated [60]- and [70]fullerenes in the gas pha se are reported.
