New [3:3]hexakisadducts3, 6, and 7 have been synthesized by a stepwise addition of two tripodal malonate tethers to pristine [60]fullerene. For the first time, [3:3]hexakisadducts of two sets of asymmetrically substituted malonate addends could be prepared as single in/out isomers by following this synthetic protocol. Thereby, foursphericallydefinedaddendzones I–IV were created with various similar

A pentakis-adduct of C60 with an incomplete octahedral addition pattern was synthesised via a one-pot procedure using a tether equipped with five malonate moieties. The five-fold Bingel cyclopropanation of C60 was completely regioselective and afforded a chiral, C2-symmetric pentakis-adduct which was easily separated by column chromatography on SiO2.
