METHOD OF SYNTHESIS OF 1-ARYL(ALKYL)-2-MAGNESIUM HALOGEN(60)- -FULLERENES Russian patent published in 1999 - IPC

Abstract RU 2135506 C1

FIELD: organic chemistry. SUBSTANCE: invention describes a method of synthesis of 1-aryl(alkyl)-2-magnesium halogen(60)-fullerenes of the general formula (I) where n = 1-4; C60 - new allotropic carbon modification; R is Ph, p-C6H13, p-C7H19 characterized in that toluene fullerene-C60 solution is interacted with an excess of ether solution of aryl(alkyl)magnesium halide RMgHal where R is Ph, p-C6H13, p-C7H15; Hal is Br, Cl at mole ratio = 1:(60-120) in the presence of zirconacene dichloride (Cp2ZrCl2) as a catalyst taken at amount 1-3 mole% with respect to RMgHal. Reaction is carried out in argon atmosphere at the room temperature under normal pressure for 8-12 h. Synthesized fullerenes can be used in fine organic and organometallic synthesis and products of their functionalization - as physiologically active substances, extractants, sorbents, addition agents, photosensitive materials. EFFECT: improved method of synthesis. 1 tbl, 1 ex
