Higher fullerenes fluorination

Apart from these, a number of reactions, e.g. ozonation [150], hydrogenation [151], fluorination [152], and the formation of methylene adducts by reaction with THF [153], have led to various mixtures of higher fullerene derivatives. Finally, as the methods for production and purification of endohedral fullerene derivatives are being improved, the exohedral functionalization of Qq [70, 73, 74] and C70 [73] cages containing noble gas atoms, and of endohedral metallo-fullerenes [64,154] emerge as new fields of fullerene chemistry. 

HalogenofuUerenes can also be generated with chlorine, the next higher homolog. The synthetic methods are similar to those for fluorination. Both chlorine and halogenochlorides may be employed, but as with fluorine, complex mixtures are often obtained instead of separable compounds. Moreover chloro-fullerenes are less stable than their fluoro-analogs, they are prone to hydrolysis...
