METHOD OF PREPARING N-BUTYL SUBSTITUTED C. FULLERENES Russian patent published in 1999 - IPC

Abstract RU 2134255 C1

FIELD: organic chemistry, more particularly fine organic synthesis, medicine and agriculture, and addition agents of oil. SUBSTANCE: in order to prepare n-butyl substituted C60 fullerenes, toluene solution of fullerene is reacted with excess amount of ether solution of di(n- butyl) magnesium at C60:(n-Bu2Mg) molar ratio of 1:(35-90) in the presence of zirconacene dichloride as catalyst in amount 1-3 mole % with respect to n-Bu2Mg. Reaction is carried out in argon atmosphere under normal conditions for 8-12 h. Reaction mixture is then treated with 5-% aqueous HCl. EFFECT: more efficient preparation method. 1 ex, 1 tbl
