Abstract RU 2459805 C2

FIELD: chemistry.

SUBSTANCE: invention relates to organic chemistry, and specifically to a method of producing sulphur-containing homofullerenes of general formula (1): R = Am (pentyl), Cy (cyclohexyl), which is characterised by that C₆₀-fullerene reacts with sulphur-containing diazoalkanes, produced in situ via oxidation of corresponding hydrazones of ketosulphides with MnO₂, of general formula N₂C(Me)CH(Me)CH₂S-R, where R = Am (pentyl), Cy (cyclohexyl), in the presence of a three-component catalyst {Pd(acac)₂:2PPh₃:4Et₃Al}, taken in molar ratio C₆₀ : diazocompound : Pd(acac)₂ : PPh₃ : Et₃Al=0.01:(0.01-0.03):(0.0015-0.0025):(0.003-0.005):(0.006-0.01), preferably 0.01:0.02:0.002:0.004:0.008, in o-dichlorobenzene as a solvent at temperature 20°C for 0.25-1.0 hours.

EFFECT: method of obtaining novel sulphur-containing homofullerenes, which can be used as effective nanocomponent additives for industrial oil, complexing agents, as well as novel optoelectronic materials.
