Abstract

Suzuki-Miyaura cross-coupling reactions of 5,11-dibromotetracene with arylboronic acids, using a triethylammonium-tagged palladium(II) diphenylphosphine complex as catalyst in a pyrrolidinium-based ionic liquid (IL), allowed the preparation of new 5,11-diaryl-substituted tetracenes in good to excellent yields. The synthesis of the new 5,11-diboronic-tetracene bis-pinacolate ester and its use in Suzuki-Miyaura cross-coupling reaction with aryl bromides in IL are also reported. © 2011 American Chemical Society.
