Individual gaseous species of fullerene chlorides have been successful
ly generated in a molecular beam. Knudsen cell mass spectrometry has b
een used to detect C60C2n (n = 0...9), C70C2m (m = 0...7) in the vapou
r over the system C-60/C-70 (extract) with CrCl3 FeCl3 . 6H(2)O, FeCl3
(anhydrous) and CuCl2 (anhydrous) at temperatures from 520 to 720 K.
Bond dissociation enthalpies for the fullerene chlorides have been est
