Process for the preparation of 3'-methyl-3'-furyl- or 3'-methyl-3'-thienyl-3'H-cyclopropa 1,9 (C60-Ih) 5,6 fullerenes

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to a method of producing 3'-methyl-3'-furul- or 3'-methyl-3'-thienyl-3'H-cyclopropa[1,9](C₆₀-I_h)[5,6]fullerenes of formula (1), ;, ;which can be used as effficient nano-component additives for industrial oil, as complexing agents and as novel optoelectronic materials. The method involves reaction of fullerene (C₆₀) with heterocycle-containing diazoalkanes which are generated in situ by oxidation of hydrazones of 2-acetyl furan or 2-acetyl thiophene with MnO₂, 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:(0.01-0.03):(0.0015-0.0025):(0.003-0.005):(0.006-0.01), at temperature of 20°C for 0.25-1.0 hours. Output is equal to 36-60%.;EFFECT: method of producing 3'-methyl-3'-furyl- or 3'-methyl-3'-thienyl-3'H-cyclopropa[1,9](C₆₀-I_h)[5,6]fullerenes is disclosed.;1 cl, 1 tbl
