Abstract/OtherAbstract:
1,2-Dihydromethano[60]fullerene and its congeners have attracted much interest, but they have only been synthesized in very low yield because of several insurmountable problems. A new three-stage synthesis involving addition of a silylmethylmagnesium chloride to [60]- and [70]fullerene and oxidation of the anionic intermediate with CuCl2 afforded the methano[60]fullerene in 90% and 70% overall yield, respectively. The reaction with 1,4-diorgano[60]fullerene also proceeded smoothly to give a diastereomerically pure 56π-electron fullerene, which has a higher LUMO level than the parent fullerene, and gave a higher open circuit voltage as well as a better power conversion efficiency when fabricated into an organic photovoltaic device.
