METHOD FOR SELECTIVE SYNTHESIS OF 1'-[2-METHYLSULPHANYL)-ETHYL]-1'-ETHYLFORMYLCYCLOPROPA [2'3':1,9] (C-I) [5,6] FULLERENE Russian patent published in 2012 - IPC C07C319/12 C07C321/04 C01B31/02

Abstract RU 2447062 C2

FIELD: chemistry.

SUBSTANCE: invention relates to organic chemistry. The method involves reaction of C₆₀-fullerene with 1-[2-(methylsulphanyl)ethyl]diazoacetic ether in o-dichlorobenzene (o-DCB) in the presence of a three-component catalyst {Pd(acac)₂:4PPh₃:4Et₃Al} at temperature 80°C for 0.2-1.0 hours. 1'-[2-(methylsulphanyl)-ethyl]-1'-ethylformylcyclopropa[2',3':1,9](C₆₀-I_h)[5,6]fullerene (1) is obtained with output 31-55%.

EFFECT: obtaining functionally substituted fullerenes, which can be used as effective nanocomponent additives to industrial oil, as well as novel optoelectronic materials.
