METHOD OF PRODUCING OPTICALLY ACTIVE SPIRO-HOMOFULLERENES Russian patent published in 2012 - IPC C07C13/64 C07C2/86 B01J31/22 B01J31/26 B01J31/16 B01J31/14 B01J31/24

Abstract RU 2455273 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing optically active spiro-homofullerenes of formula (1) and (2): characterised by that C₆₀-fullerene reacts with optically active diazocompounds generated in situ via oxidation of hydrazones of (-)-menthone and D-(+)-camphor with MnO₂, in o-dichlorobenzene in the presence of a three-component catalyst system Pd(acac)₂-PPh₃-Et₃Al, taken in molar ratio C₆₀ : optically active hydrazone : Pd(acac)₂ : PPh₃ : Et₃Al=0.01:(0.01-0.02):(0.0015-0.0025):(0.003-0.005):(0.006-0.01), at room temperature (about 20°C) for 1-2 hours.

EFFECT: method is distinguished from existing methods by high output of end products and selectivity of the reaction, use of a palladium complex in catalytic amounts, as well as low power consumption.
