title: 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.
