T h -C60F24

The regioselective fluorination of T h -C60Br24 with XeF2 in anhydrous HF at 25 °C produced T h -C60F24, which is isostructural with T h -C60Br24. The compound, the first example of a fluorofullerene with a noncontiguous pattern of F-bearing sp3 C atoms, was characterized by EI and ESI mass spectrom...

Description
Summary:The regioselective fluorination of T h -C60Br24 with XeF2 in anhydrous HF at 25 °C produced T h -C60F24, which is isostructural with T h -C60Br24. The compound, the first example of a fluorofullerene with a noncontiguous pattern of F-bearing sp3 C atoms, was characterized by EI and ESI mass spectrometry and by 19F NMR (single resonance at δ −144 for all 24 F atoms), 13C NMR (two resonances at δ 145.9 (CC) and δ 83.5 (C−F; J CF = 212 Hz), and FTIR spectroscopy. DFT calculations revealed that at least two other isomers of C60F24 are more stable than T h -C60F24 by ≥280 kJ mol-1, demonstrating that T h -C60F24 is a kinetically stable fluorofullerene.
