METHOD OF OBTAINING POLYHYDRO[60]FULLERENES Russian patent published in 2009 - IPC C07C13/64 C07C5/02 B01J21/02 B01J21/06 B01J31/14

Abstract RU 2348601 C1

FIELD: chemistry.

SUBSTANCE: invention concerns method of obtaining polyhydro[60]fullerenes of formula (1): , involving fullerene C₆₀ interaction with diisobutylaluminum chloride (i-Bu₂AlCl) in the presence of zirconocene dichloride catalyst (Cp₂ZrCl₂) at molar ratio of C₆₀:i-Bu₂AlCl:Cp₂ZrCl₂=1:(55-65):(0.15-0.25), preferably 1:60:0.20, in argon atmosphere in the absence of light at room temperature of 60-100°C and atmospheric pressure in toluene medium for 1-5 hours, with further hydrolysis of reaction mass. The method allows obtaining total 77-91% output of polyhydro[60]fullerene after reaction mass hydrolysis.

EFFECT: improved method.
