Phenanthro[1,2-b:8,7-b']dithiophene (PDT) was prepared via Suzuki-Miyaura or Negishi cross-coupling of a 2-thienylboron or -zinc compound with 1,4-dibromobenzene, followed by Lewis acid-catalyzed regioselective cycloaromatization of the epoxide. A series of 2,9-dialkylated phenanthro[1,2-b:8,7-b']dithiophene (PDT) derivatives could also be synthesized in good yields by Suzuki-Miyaura coupling of the brominated PDT with alkylboranes by introducing linear alkyl substituents.
