FIELD: chemistry.
SUBSTANCE: method of producing functionally substituted fullerenes which can be used as complexing agents, sorbents, biologically active compounds, as well as in making new materials with given properties. The method involves combined production of 1'-ethylformyl-(C60-Ih)[5,6]fullero[2',3':1,9]cyclopropane and 1'a-ethylformyl-1'a-carba-1'(2')a-homo(C60-Ih)[5,6]fullerene with general formula 1 and 2
by reacting C60-fullerene with diazoacetic ester (N2CHCOOEt), where the reaction is carried out in o-dichlorobenzene in the presence of a three-component catalyst {Pd(acac)2: 2PPh3: 4Et3Al}, taken in molar ratio C60: diazoacetic ester: : Pd(acac)2: PPh3: Et3Al=0.01:(0.03-0.07):(0.0005-0.0015):(0.001-0.003):(0.002-0.006), preferably 0.01:0.05:0.001:0.002:0.004, at temperature of 80°C for 0.5-1.5 hours. 1'-ethylformyl-(C60-Ih)[5,6]fullero[2',3':1,9]cyclopropane (1) and 1'a-ethylformyl-1'a-carba-1'(2')a-homo(C60-Ih)[5,6]fullerene (2) are obtained with total output of 44-68%.
EFFECT: method is distinguished from known methods by higher output of end products, use of a palladium complex in catalytic amounts, carrying out the reaction in a readily available solvent.
