Towards Sixfold Functionalization of Buckminsterfullerene (C60) at Fully Addressable Octahedral Sites

Selective C60‐functionalizations that provide access to unusual multifunctional molecules are of interest in the construction of highly organized three‐dimensional assemblies. The temporary “masking” of three of the most reactive sites on C60 by a bisdiene tether has allowed the facile and high‐yielding formation of the fully differentiated trisadduct 1 and the interesting hexaadduct 2.
