FIELD: chemistry. ^ SUBSTANCE: present invention relates to a method of producing (C60-Ih)[5,6]fullero[2',3':1,9]cyclopropan-1'-yl(cycloalkyl)methanones of general formula (1): n=1; 2; 3, which can be used as components of high-energy fuels, as well as nanomaterials for preparing modern additives for heavily loaded mechanisms and machines and starting substances in production of medicinal agents. The method involves reaction of C60-fullerene with 2-oxo-2-cycloalkyl diazoethanes (N2CHC(O)cycloalkyl) in o-dichlorobenzene (o-DCB) in the presence of a three-component catalyst {Pd(acac)2 : 2PPh3:4Et3Al}, taken in molar ratio C60:2-oxo-2-cycloalkyl diazoethane:Pd(acac)2:PPh3:Et3Al = 0.01:(0.03-0.07):(0.001-0.003):(0.002-0.006):(0.004-0.012), preferably 0.01:0.05:0.002:0.004:0.008, at temperature 80C for 0.5-1.5 hours. ^ EFFECT: method enables to obtain desired products with high output. ^ 1 tbl, 9 ex |
