  [2 + 2] Cycloaddition of Fullerenes with Electron-Rich Alkenes and Alkynes

  摘要：

  Photochemical [2 + 2] cycle addition of C-60 with N,N-diethyl-4-methyl-3-penten-1-yn-1-amine (1) afforded the stable C-60-fused cyclobutenamine 2 which underwent self-sensitized photooxidation to dihydrofullerenone amide 4 in high yield. Fullerenes C-60 and C-70 react thermally with tetraalkoxyethylenes to give dihydrofullerene cyclobutanediketals, which undergo a clean cyclo-reversion to fullerenes on irradiation with visible or UV light. Attempted hydrolysis of the ketals was unsuccessful, but treatment of 1,2-(6161,62,62-tetraethoxycyclobutano)dihydro[60]fullerene (8) with TMSI gave ring-contracted product 11 (by cleavage of the C-C bond to the fullerene fragment) along with reduction product 12.
