Abstract
A selective and efficient method for the synthesis of previously unknown mono-adducts of the C60 fullerene with fused morpholine moieties has been developed based on the reaction of C60 with amino alcohols, including biogenic amines (2-aminoethanol, 2-amino-1-phenylethanol, noradrenaline, and adrenaline), in a mixed solvent (toluene/DMF) at room temperature under air and ultrasonication. The radical anion C60•‒ (g = 2.0004 and ΔH1/2 = 3.4 G) was detected as a key intermediate by the EPR method upon the synthesis of the C60–morpholine adduct. This intermediate results due to the one-electron transfer from 2-aminoethanol onto the C60 core.
