New sonochemical reactions of the C60 fullerene with amino alcohols yielding morpholine–C60 adducts: Fullerenes, Nanotubes and Carbon Nanostructures: Vol 0, No 0


A selective and environment friendly technique for the synthesis of beforehand unknown mono-adducts of the C60 fullerene with fused morpholine moieties has been developed primarily based on the response of C60 with amino alcohols, together with biogenic amines (2-aminoethanol, 2-amino-1-phenylethanol, noradrenaline, and adrenaline), in a blended solvent (toluene/DMF) at room temperature underneath air and ultrasonication. The novel anion C60•‒ (g = 2.0004 and ΔH1/2 = 3.4 G) was detected as a key intermediate by the EPR technique upon the synthesis of the C60–morpholine adduct. This intermediate outcomes because of the one-electron switch from 2-aminoethanol onto the C60 core.
