Bridging pyrrole and selenophene chemistries : Molecular assemblies have been developed that allow scrutiny of the electronic communication between pyrrole and selenophene nuclei. Divergent syntheses of 2‐(selenophen‐2‐yl)pyrroles and their N ‐vinyl derivatives from available 2‐acylselenophenes and acetylenes in a one‐pot procedure have been devised (see scheme), which provide access to these exotic heterocyclic ensembles.The divergent syntheses of 2‐(selenophen‐2‐yl)pyrroles and their N ‐vinyl derivatives from available 2‐acylselenophenes and acetylenes in a one‐pot procedure make these exotic heterocyclic ensembles accessible. Now we face a potentially vast area for exploration with a great diversity of far‐reaching consequences including conducting electrochromic polymers with repeating of pyrrole and selenophene units (emerging rivalry for polypyrroles and polyselenophenes), the synthesis of functionalized pyrrole–selenophene assembles for advanced materials, biochemistry and medicine, exciting models for theory of polymer conductivity.
