Synthesis and Structure of the Highly Chlorinated [60]Fullerene C₆₀Cl₃₀ with a Drum‐Shaped Carbon Cage

Abstract

Chlorination of C60 with SbCl5, ICl, or ICl3 at 220–250 °C gives the highly chlorinated fullerene C60Cl30. The carbon cage of the C60Cl30 molecule has a unique cylindrical shape (see picture), composed of two aromatic six-membered rings located opposite each other and one equatorial aromatic 18π trannulene belt. DFT calculations suggest that C60Cl30 is the final product of [60]fullerene chlorination.
