METHOD FOR COMBINED PRODUCTION OF 1'-ETHYLFORMYL-(C₆₀-I_h)5,6FULLERO 2',3':1,9CYCLOPROPANE AND 1'a-ETHYLFORMYL-1'a-CARBA-1'(2')a-HOMO(C₆₀-I_h)5,6FULLERENE

摘要

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-I_h)[5,6]fullero[2',3':1,9]cyclopropane and 1'a-ethylformyl-1'a-carba-1'(2')a-homo(C₆₀-I_h)[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-I_h)[5,6]fullero[2',3':1,9]cyclopropane (1) and 1'a-ethylformyl-1'a-carba-1'(2')a-homo(C₆₀-I_h)[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.;1 tbl, 7 ex
