A novel synthesis of 2,3-substituted benzothiophenes is reported, involving a tandem base-mediated condensation of o-iodoarylacetonitriles/acetates/ketones with (hetero)aryldithioesters and an intramolecular C-S bond formation. The reaction affords divers

Efficient synthesis of benzo[b]thiophenes from o-halophenyl acetonitrile has been achieved. This novel one-pot procedure involves CuI and pivalic acid catalyzed C-S bond formation using dithioesters followed by a heterocyclization reaction. This efficient

Direct 3-substituted benzothiophene arylation using a Heck-type reaction with Pd(OAc)2/n-Bu4NBr as a catalytic system is reported. This reaction was found to perform relatively fast whatever the electron-donating or the electron-withdrawing group at position 3. We also extended this reaction to several aromatic halides, such as benzene, naphthalene and pyridine derivatives, synthesising new 2-arylbenzo[b]thiophenes in moderate to good yields.
