METHOD OF OBTAINING 2,5-DIALKYL-3,4-FULLERO[60]TETRAHYDROTHIOPHEN-1-ONS Russian patent published in 2008 - IPC C07D333/78 C01B31/02

Abstract RU 2342377 C2

FIELD: chemistry.

SUBSTANCE: claimed invention relates to field of organic chemistry, namely to method of obtaining 2,5-dialkyl-3,4-fullero[60]tetrahydrothiophen-1-ons of general formula (I) . Essence of method lies in interaction of fullereneC₆₀ with dialkylsufoxides in presence of catalyst Cp₂ZrCl₂ in toluol medium at temperature 140-160°C during 5-7 hours. Target product output is 40-65%.

EFFECT: obtaining compounds, which can be used as complex-forming agents, sorbents, biologically active compounds, as well as in creation of novel materials with set electronic, magnetic and optical properties.
