Synthesis of mono- and bis-arylated 3,4-(ethylenedioxythiophenes) via direct palladium catalyzed arylation reactions

The synthesis of arylated/heteroarylated 3,4-ethylenedioxythiophene derivatives is reported using a straightforward palladium mediated Heck coupling of 3,4-ethylenedioxythiophene with various aryl/heteroaryl halides.
