METHOD OF SYNTHESIS OF ETHYL-CONTAINING C-FULLERENES Russian patent published in 1999 - IPC

Abstract RU 2133727 C1

FIELD: organic chemistry, chemical technology. SUBSTANCE: invention relates to the synthesis of novel hydrocarbon compounds, namely, ethyl-containing fullerenes of the general formula εtnC60Hn where n = 1-4; C60 - a new allotropic modification of carbon. Method involves an interaction of fullerene toluene solution with an excess of ethylmagnesium bromide (εt2MgBr) or ethylmagnesium chloride (EtMgCl) ether solution in the presence of zirconacene dichloride (Cp2ZrCl) as a catalyst which is taken at amount 1-3 mole% with respect to EtMgHal. The mole ratio C60 : : EtMgHal = 1:(30-300). Process is carried out under argon atmosphere, at normal condition for 8-16 h followed by treatment of reaction mass with 5% aqueous hydrochloric acid. Synthesized compounds can be used in fine organic synthesis and as the parent semiproducts for producing biologically active substances for medicine, agriculture and oil addition agents. EFFECT: improved method of synthesis. 1 tbl
