Abstract

A variety of [70]fullerene derivatives bearing three organic groups C₇₀R₃H (1, R = aryl, methyl) have been synthesized in 90-99% isolated yield by the reaction of [70]fullerene with a Grignard reagent in the presence of CuBr·S(CH₃)₂. Deprotonation of C₇₀R₃H with a metal alkoxide gave the corresponding metal complex M(η⁵-C₇₀R₃)[M = K (2), Tl (3)]. X-ray crystallographic analysis as well as theoretical study revealed the nature of the 68π-electron ligand, C₇₀R₃^-.
