2024 J org chem - Thiepins are conjugated seven-membered ring systems with a thioether in the macrocycle. Such (annulated) thiepins are designed to undergo bent-to-planar transformation driven by aromatization under electrochemical control. Sulfur extrusion on extended thiepin systems may find utility in peroxide sensing. See Swager and co-workers, p 999. View the article.
