Аннотация:We report three new isomers of C70(CF3)8, structurally related to p7mp-C70(CF3)10, that are inaccessible by direct trifluoromethylation, but can be easily identified among the products of the transalkylation of higher trifluoromethylfullerenes with C70. The reported compounds are characterized by UV/Vis, 1D and 2D COSY 19F NMR spectroscopy, and DFT calculations. A rather unusual addition pattern is observed in p6,i-C70(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.
