A metal‐free radical cyclization of arenesulfonyl chlorides with alkynes has been developed, which provides a rapid and practical access to a variety of π‐conjugated benzothiophenes with a broad reactive functional group tolerance. Furthermore, dialkynyl compounds could also undergo this transformation to give extended π‐systems in good yields.
