METHOD OF PRODUCING CHOLESTERYL CYCLOPROPA[1,9](C-I)[5,6]FULLERENE-3'CARBOXYLATE Russian patent published in 2012 - IPC C01B31/02 B82B3/00 C07C15/24

Abstract RU 2447018 C2

FIELD: chemistry.

SUBSTANCE: invention relates to organic chemistry and can be used to produce complexing agents, sorbents, biologically active compounds, as well as novel materials with given properties. C₆₀-fullerene reacts with cholesteryl diazoacetate in o-dichlorobenzene in the presence of a three-component catalyst system {Pd(acac)₂:2PPh₃:4Et₃Al} at temperature 80°C for 0.5-1.5 hours. Molar ratio C₆₀:diazocompound:Pd(acac)₂:PPh₃:Et₃Al}=1:(3-7):(0.1-0.3):(0.2-0.6):(0.4-1.2), preferably 1:5:0.2:0.4:0.8. Cholesteryl cyclopropa[1,9](C₆₀-I_k,)[5,6]fullerene-3'-carboxylate of formula

is obtained with output 44-68%.

EFFECT: high efficiency of the method.
