The reaction of C(60) with propionaldehyde (butyraldehyde or phenylacetaldehyde) and MeONa-MeOH or EtONa-EtOH in anhydrous chlorobenzene in the presence of air at room temperature unexpectedly gave rare fullerene acetals 2aa-cb, while the reaction of C(60) with acetone (acetophenone, cyclohexanone, or cyclopentanone) and MeONa-MeOH or EtONa-EtOH under the same conditions afforded the uncommon fullerene ketals 4aa-db. A possible reaction mechanism for the formation of the fullerene acetals and ketals is proposed based on further experimental results.
在室温下，于无水氯苯中，在空气存在的条件下，C(60) 与丙醛（丁醛或苯乙醛）以及甲氧基钠 - 甲醇或乙氧基钠 - 乙醇发生反应，意外地生成了罕见的富勒烯缩醛 2aa - cb；而在相同条件下，C(60) 与丙酮（苯乙酮、环己酮或环戊酮）以及甲氧基钠 - 甲醇或乙氧基钠 - 乙醇反应，则得到了不常见的富勒烯缩酮 4aa - db。基于进一步的实验结果，提出了富勒烯缩醛和缩酮形成的可能反应机理。
