METHOD OF PRODUCING (C-C)[5,6]FULLERO[2',3':1,9]CYCLOPROPANE Russian patent published in 2011 - IPC C07C13/64 C07C2/86 B01J31/22

Abstract RU 2417979 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing (C₆₀-I_h)[5, 6]fullero[2',3':1,9]cyclopropane of general formula (1): , characterised by that C₆₀-fullerene reacts with diazomethane (CH₂N₂), generated in situ from N-methyl-N-nitrosourea and aqueous solution of KOH in chlorobenzene in the presence of a palladium catalyst (Pd(acac)₂), taken in molar ratio C₆₀: N- methyl-N-nitrosourea: Pd(acac)₂=0.01:(0.01-0.05):(0.0015-0.0025) and 0.1 ml of 40% aqueous solution of KOH, preferably 0.01:0.03:0.002, at temperature 40°C for 0.5-1.5 hours.

EFFECT: use of the present method enables to use a palladium complex in catalytic amounts and obtain an end product with higher output.
