METHOD FOR PREPARING 1-ETHYL-3,3-DIALKYL-6,7-FULLERENO[60]CYCLOHEPTA-2-OX-1-ALANES Russian patent published in 2003 - IPC

Abstract RU 2206570 C1

FIELD: organometallic chemistry, chemical technology. SUBSTANCE: invention relates to method for preparing novel organic aluminum derivatives of the formula (I) given in the description that can be used as extractants, sorbents, additives and physiologically active substances. Method involves interaction of fullerene[60] with excess of EtAl₃ in the presence zirconacene dichloride of the formula Cp₂ZrCl₂ as a catalyst under argon atmosphere at the room temperature, in toluene medium for 24 h followed by addition of copper monochloride CuCl as a catalyst at temperature 15 C taken in the amount 0.5-1 mole % to triethyltriethylaluminium and ketone of the formula: RR¹CO where R is CH₃, R¹ is C₂H₅; R is CH₃, R¹ is i-C₄H₉; R is C₂H₅, R¹ is n-C₄H₉ taken in equimole amount to triethylaluminium followed by stirring reactive mass under argon atmosphere at the room temperature for 6-10 h. Invention provides preparing novel organic aluminum compounds used as sorbents, additive and extractants. EFFECT: improved preparing method, valuable properties of compounds. 1 tbl, 1 ex
