1,9-[3',3'-BIS(HYDROXYMETHYL)MORPHOLINO]-1,9-DIHYDRO-(C-I)[5,6]FULLERENE AS A COMPLEXING AGENT AND METHOD FOR ITS PREPARATION Russian patent published in 2023 - IPC C07D265/34 C01B32/154

Abstract RU 2807926 C1

FIELD: organic chemistry of heterocyclic compounds.

SUBSTANCE: invention relates to a method for producing 1,9-[3',3'-bis(hydroxymethyl)morpholino]-1,9-dihydro-(C₆₀-I_h)[5,6]fullerene of formula (1). The essence of the method is the interaction of tris(hydroxymethyl)aminomethane with fullerene C₆₀ in the presence of solid LiOH and Pb(CH₃COO) ₄ in air at the molar ratio C₆₀: tris(hydroxymethyl)aminomethane:LiOH:Pb(CH₃COO)₄ = 1:86-200:2-105:2-17 in toluene:DMF=8:1, taken in a volumetric ratio, for 1-2 hours under ultrasound at 22 kHz, 20 W.

EFFECT: development of a method for the selective production of 1,9-[3',3'-bis(hydroxymethyl)morpholino]-1,9-dihydro-(C₆₀-I_h)[5,6]fullerene of formula (1), which can be used as a complexing agent with Ca(II) and Mg(II) ions.
