Chemical and electrochemical reduction of the highly chlorinated fullerenes C60Cl24 and C60Cl30

Fully aromatic C 60 Cl 30 is much more difficult to reduce than non-aromatic C 60 Cl 24 ; the anion radicals C 60 Cl n − (n = 24, 30) are unstable and undergo rapid decomposition with loss of Cl − anions and partial substitution of chlorine atoms by organic groups.
