摘要：

Diarylalkynes are readily transformed in 3-chlorobenzo[b]thiophenes in a two-step electrophilic addition-cyclization procedure that runs highly efficiently in solution or in the solid phase. The heteroaromatic carbon-chlorine bond participates in palladium-catalyzed Suzuki-Miyaura or Buchwald-Hartwig cross-couplings to give, in a single step, 2,3-disubstituted derivatives of pharmacological relevance.
