Thermolysis of a mixture of C60 and the cyclopropenone acetal 1a or 1b gives the methanofullerene 4a or b, whereas the ethyl-substituted compound 1c gives the cyclopentenone acetal 6. The thermal stability of 4 and the semi-empirical molecular orbital calculations performed for the parent methanofullerenes and fulleroids indicated that the fulleroid structure such as 5 may be unstable.
