Abstract

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 protocol has the advantages of one-pot synthesis, short reaction time, good yields (62–78%) and operational simplicity.
