An isomeric mixture of C70(C2F5)10 has been synthesized by a high temperature reaction of C70 with C2F5I in a glass ampoule followed by HPLC separation. Partial thermal decomposition of C70(C2F5)10 has been performed to yield a complex mixture of lower derivatives. The molecular structures of nine isomers of C70(C2F5)8 isolated therefrom plus two new isomers of C70(C2F5)10 have been determined by means of single crystal X-ray diffraction. We discuss these newly obtained structures in terms of relative energies and possible formation pathways.
通过在玻璃安瓿中将C70与C2F5I进行高温反应，随后进行高效液相色谱分离，合成了C70(C2F5)10的异构体混合物。对C70(C2F5)10进行了部分热分解，以产生较低衍生物的复杂混合物。通过单晶X射线衍射确定了从中分离出的C70(C2F5)8的九种异构体以及C70(C2F5)10的两种新异构体的分子结构。我们根据相对能量和可能的形成途径讨论了这些新获得的结构。
