| Abstract: | Spirohomofullerenes were synthesized by cycloaddition of cage and polycyclic diazoalkanes generated in situ by oxidation of hydrazones of camphor, 2-adamantanone, and cholestane-3-one to C60 fullerene in the presence of the Pd(acac)2-2PPh3-4Et3Al three-component catalyst. It was found that the spiro-homofullerenes obtained from hydrazones of 2-adamantanone and cholestane-3-one and C60 fullerene do not undergo thermal isomerization to the corresponding spiro-methanofullerenes. |
