Difluoromethylenation of C60 with thermally decomposed CF2ClCO2Na provides novel C60(CF2) and C60(CF2)2 compounds with unique [6,6]-open structures. A theoretical survey of CF2 derivatives of C60 demonstrates that carbon cage opening can be controlled via charging of the molecule and that the thermodynamically preferable structures combine the trend to form open isomers with the compactness of the addition motifs, which results in the formation of windows in the fullerene cage.
用热分解的CF2ClCO2Na对C60进行二氟亚甲基化反应可得到具有独特[6,6]-开环结构的新型C60(CF2)和C60(CF2)2化合物。对C60的CF2衍生物进行的理论研究表明，碳笼的打开可以通过分子的电荷来控制，并且热力学上更有利的结构将形成开环异构体的趋势与加成基团的紧密性结合起来，这导致在富勒烯笼中形成窗口。
