Synthesis of C3 Benzo[1,2‐e:3,4‐e′:5,6‐e′′]tribenzo[l]acephenanthrylenes (“Crushed Fullerene” Derivatives) by Intramolecular Palladium‐Catalyzed Arylation

Abstract

The C₆₀ polyarenes 4, 5, 18 a, and 18 b have been synthesized from truxene by triple alkylation at C5, C10, and C15 followed by a palladium‐catalyzed intramolecular arylation. The synthesis of “crushed fullerene” C₆₀H₃₀ (2) is the most efficient reported to date and proceeds in 33 % overall yield.
