Towards Sixfold Functionalization of Buckminsterfullerene (C(60)) at Fully Addressable Octahedral Sites

Selective C(60)-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 C(60) by a bisdiene tether has allowed the facile and high-yielding formation of the fully differentiated trisadduct 1 and the interesting hexaadduct 2.
