METHOD FOR COMBINED SYNTHESIS OF 1'-[2-(METHYLSULPHANYL)ETHYL]-1'-ETHYLFORMYL-(C-I)[5,6]FULLERO[2',3':1,9]CYCLOPROPANE AND 1'a-[2-(METHYLSULPHANYL)ETHYL]-1'a-ETHYLFORMYL -1'a-CARBA-1'(2')a-HOMO(C-I)[5,6]FULLERENE Russian patent published in 2012 - IPC C07C323/22

Abstract RU 2440337 C2

FIELD: chemistry.

SUBSTANCE: invention relates to organic chemistry and specifically to a method for combined synthesis of 1'-[2-(methylsulphanyl)ethyl]-1'-ethylformyl-(C₆₀-I_h)[5,6]fullero[2',3':1,9]cyclopropane (1) and 1'a-[2-( methylsulphanyl)ethyl]-1'a-ethylformyl -1'a-carba-1'(2')a-homo(C₆₀-I_h)[556]fullerene (2) , involving 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: 2PPh₃: 4Et₃Al}, taken in molar ratio C₆₀: diazo-compound : Pd(acac)₂ : PPh₃ : Et₃Al = 0.01 : (0.03-0.07) : (0.0015-0.0025) : (0.003-0.005) : (0.006-0.01), preferably 0.01:0.05:0.002:0.004:0.008, at temperature 80°C for 0.2-1.0 hours.

EFFECT: method of producing novel compounds which can be used as complexing agents, sorbents, biologically active compounds, as well as when producing novel materials with given properties.
