METHOD FOR COMBINED SYNTHESIS OF (C₆₀-I_h)5,6FULLERO2',3':1,9CYCLOPROPANE AND 1Т(2')a-HOMO(C₆₀-I_h)5,6FULLERENE

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to a method for combined synthesis of C₆₀-I_h)[5,6]fullero[2',3':1,9]cyclopropane and 1'(2')a-homo(C₆₀-Ih)[5,6]fullerene of general formulae and by reacting C₆₀-fullerene with an ether solution of diazomethane (CH₂N₂) and subsequent conversion of the obtained fulleropyrazoline into a formula (1) and (2) compound, characterised by that both reactions take place simultaneously during reaction of C₆₀-fullerene with diazomethane in toluene in the presence of a palladium catalyst (Pd(acac)₂), taken in molar ratio C₆₀: diazomethane: Pd(acac)₂=0.01:(0.01-0.03):(0.0015-0.0025), preferably 0.01:0.02:0.002, at temperature 40°C for 0.5-1.5 hours.;EFFECT: obtaining end products with higher output.;1 cl, 1 tbl, 7 ex
