METHOD OF PRODUCING CYCLOALKYLIDENEHOMO(C-C)[5,6]FULLERENE Russian patent published in 2011 - IPC C07C13/64 C07C2/86 B01J31/22 B01J31/26 B01J31/16 B01J31/14 B01J31/24

Abstract RU 2417980 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing cycloalkylidenehomo(C₆₀-I_h)[5,6]fullerenes of general formula (1): n=1,2,3,4, characterised by that C₆₀-fullerene reacts with cyclic diazo-compounds, generated in situ from corresponding unsubstituted hydrazones () using Ag₂O, in o-dichlorobenzene in the presence of a three-component catalyst system Pd(acac)₂-2PPh₃-4Et₃Al, taken in molar ratio C₆₀ : unsubstituted hydrazone : Pd(acac)₂-2PPh₃-4Et₃Al = 0.01 :(0.01 -0.02):(0.0015-0.0025), at room temperature (approximately 20°C) for 20-40 minutes.

EFFECT: method differs 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.
