METHOD OF SELECTIVE RECEPTION OF ISOPROPYLINE 5'-ARYL-1'N-PYRROLIDINO[3',4':1,9](C60-IH)[5,6]FULLERENE-2'-CARBOXYLATES Russian patent published in 2017 - IPC C07D207/16

Abstract RU 2629752 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a method for preparation of fulleropyrrolidines that can be used as complexing agents, sorbents, biologically active compounds, as well as for creation of new materials with specified electronic, magnetic, and optical properties. A method for selective preparation of isopropyl-5'-aryl-1'H-pyrrolidino[3',4':1,9](C_60-I_h)[5,6]fullerene-2'-carboxylates of the general formula is characterised by C₆₀-fullerene reaction with ethyl isocyanoacetate of the formulaEtO₂CCH₂N⁺≡C in chlorobenzene under the action of the Ti(OiPr)₄ catalyst in the presence of ArMgBr (where Ar = Ph, 2-MePh), taken in the molar ratioof C₆₀:Isocyanoacetate:Ti(OiPr)₄:ArMgBr = 1:(2-6):(1-5):(6-10), at a temperature of 100°C for 5-30 minutes.

EFFECT: improved method for preparation of these compounds.
