我们报道了C-70（CF 3）（8）的三种新的异构体，它们在结构上与p（7）mp-C-70（CF 3）（10）相关，它们不能通过直接三氟甲基化反应得到，但可以在更高的三氟甲基富勒烯与C-70的烷基转移反应产物中容易地鉴定出来。所报道的化合物通过UV/维斯、1D和2DCOSY（FNMR）-F-19光谱和DFT计算进行表征。在p（6），i-C-70（CF 3）（8）中观察到一种相当不寻常的加成模式，其中一个加成物与其他加成物连接得很远;加成物使相邻的不饱和键极化，使分子易于氧化。
We report three new isomers of C-70(CF3)(8), structurally related to p(7)mp-C-70(CF3)(10), that are inaccessible by direct trifluoromethylation, but can be easily identified among the products of the transalkylation of higher trifluoromethylfullerenes with C-70. The reported compounds are characterized by UV/Vis, 1D and 2DCOSY (FNMR)-F-19 spectroscopy, and DFT calculations. A rather unusual addition pattern is observed in p(6),i-C-70(CF3)(8) in which one addend is attached remotely from the others; polarization of the adjacent unsaturated bonds by the addend makes the molecule readily oxidizable.
