Abstract
Cyclometallation of C-60 fullerene with excess AlEt3 in the presence of Cp2 ZrCl2 (2 mol % with respect to [Al]) in a toluene solution at 22-23 degrees C was carried out. The reaction gave 2,3-fullerene-substituted aluminacycl opentanes, whose hydrolysis led to a mixture of hydrogen-containing ethylfu llerenes of the type HmC60Etm containing 1 to 12 ethyl groups.
