Novel pentacenequinone derivatives 3, 7, and 10 have been synthesized via Suzuki-Miyaura coupling. Derivatives 3 and 7 having OTBS groups undergo irreversible fluorideinduced cyclization to substituted higher quinones in the presence of TBAF in dry THF using one-pot, two-step strategies in moderate yields. These functionalized higher quinone derivatives are freely soluble in THF and DMSO and can be used as precursors for the synthesis of higher acene derivatives. 2011 American Chemical Society.
