Photochemical addition reactions of [60]fullerene with 1,2-ethylenediamine and piperazine

N,N′-Dimethylethylenediamine and piperazine reacted with [60]fullerene by photoinduced-electron transfer to form the adduct compounds in a short reaction time with a good yield. NMR spectroscopy showed unambiguously that derivatives were C2v symmetric structures with a 6,6 junction, and a single-electron transfer intermediate was suggested.
