An electrochemical mediator-induced intermolecular selective (3+2) annulation of readily available alkenes and alkynes/alkenes was developed. The simple and efficient method allows the synthesis of a library of decorated cyclopentenes and cyclopentanes. A preliminary mechanistic investigation was performed, which indicated that an iodine radical and carbon radicals are involved in this transformation

Atomtransferradicaladdition (ATRA) reactions are crucial for the dual functionalization of unsaturated hydrocarbons. Radical generation, pivotal in ATRA, has seen advancements from thermal to photochemical methods. Recent focus on halogen-bonding-based radical generation, including our group’s innovative photochemical approach, offers cost-effective alternatives to transition-metal-dependent photocatalysts
