四酮开笼 C-60 衍生物与元素硫在四（二甲氨基）乙烯存在下反应，得到了在孔口边缘含有硫原子的新型开放 C-60 衍生物，也是开放 C59S 衍生物的第一个例子。单晶 X 射线分析清楚地确定了这些结构，并证明水分子被封装在笼子内。揭示了这些富勒烯衍生物的孔口尺寸和电子特性。
The reaction of a tetraketo-open-cage C-60 derivative with elemental sulfur in the presence of tetrakis(dimethylamino)ethylene afforded novel open C-60 derivatives containing sulfur atom(s) in the rim of the orifice and the first example of an open C59S derivative. The single crystal X-ray analyses clearly determined these structures and demonstrated that a water molecule was encapsulated inside the cages. The orifice sizes and electronic properties of these fullerene derivatives were revealed.
