Abstract

PROBLEM TO BE SOLVED: To obtain a metal complex containing η<5> type ligand in which one of carbon five-membered ring which fullerene C60 has is converted to cyclopentadienyl ligand by reacting C70 with an organocopper reagent prepared from a Grignard reagent and a copper halide derivative. SOLUTION: A Grignard reagent of the formula RMgCl, RMgBr or RmgI (R is a 1-10C alkyl) is mixed with a copper halide reagent such as CuBr.Sme in an ether-based solvent to provide an organocopper reagent. A solution containing the organocopper reagent in an amount of 5-50 equivalents based on C60 is cooled to -10 to -30 deg.C and then, C60 is dissolved in an aromatic hydrocarbon solvent such as tetrahydrofuran or diethyl ether and cooled to -100 to -30 deg.C and added thereto and immediately, 1-5 equivalent chlorinated trimethyl silane and 5-50 equivalent hexamethylphosphoric triamide are added thereto and these components are heated at -20 to 40 deg.C and stirred for 3-50 hr to provide the objective C60 derivative of the formula.
