[1] Fluorination of aza[60]fullerene / O. V. Boltalina, T. Drewello, A. Hirsch et al. // RECENT ADVANCES IN THE CHEMISTRY AND PHYSICS OF FULLERENES AND RELATED MATERIAL, VOL 7. — Vol. 99 of ELECTROCHEMICAL SOCIETY SERIES. — ELECTROCHEMICAL SOCIETY INC 65 S MAIN ST, PENNINGTON, NJ 08534-2839 USA, 1999. — P. 462–471. Aza[60]Fullerene has been fluorinated with the transition metal fluorides MnF3 and CeF4, and in each case, the most prominent species in the volatile products is C59NF33, as shown by electron impact mass spectrometry. Thus, whereas fluorination of [GO]fullerene with these reagents produces C60F36, fluorination of aza[60]fullerene results in the addition of only 33 fluorines. This may be due to replacement of C-F by N (in one of the pentagonal rings in C60F36, that has three attached fluorines) and loss of 2F giving a second double bond, thereby creating an aromatic (6 pi) structure of high stability. The positive ion laser-desorption ionization mass spectra of the fluorinated products showed the presence of ions due to the aza derivatives of the higher fullerenes, and thus provides the first detection of these species.
