METHOD OF OBTAINING ARYL(C-I)[5,6]FULLERENE-(9H)-YL KETONES Russian patent published in 2015 - IPC C07C49/225 C07C69/78 C07C45/00 C07C67/00

Abstract RU 2540082 C2

FIELD: chemistry.

SUBSTANCE: claimed invention relates to method of obtaining aryl (C₆₀-I_h)[5,6]fullerene-1(9H)-yl ketones of generatl formula (1): , . Functionally substituted fullerenes can be applied as complexants, sorbents, biologically active compounds, as well as in creation of novel materials with specified electronic, magnetic and optic properties. Method consists in interaction of C60-fullerene with ethers of aromatic carboxylic acids of formula ArC(O)OMe (Ar = phenyl, biphenyl, in toluene under action of catalyst Ti(OiPr)₄ in presence of EtMgBr, with molar ratio C₆₀: ether: Ti(OiPr)₄: EtMgBr=1:(5-15):(5-15):(30-50), at temperature 0°C for 5-30 min.

EFFECT: invention makes it possible to obtain target products with output 44-68%.
