METHOD FOR COMBINED SYNTHESIS OF (C-I)[5,6]FULLERO[2',3':1,9]CYCLOPROPANE AND 1Т(2')a-HOMO(C-I)[5,6]FULLERENE Russian patent published in 2011 - IPC C07C13/64 C07C2/86 C07C2/66

Abstract RU 2409546 C2

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.
