Photo-oxidative Cross-Dehydrogenative Coupling-Type Reaction of Thiophenes with α‑Position of Carbonyls Using a Catalytic Amount of Molecular Iodine

Photo-oxidative Cross-Dehydrogenative Coupling-Type Reaction of Thiophenes with α‑Position of Carbonyls Using a Catalytic Amount of Molecular Iodine

A metal-free photo-oxidative intermolecular C–H/C–H coupling reaction of thiophenes is demonstrated with carbonyls using a catalytic amount of molecular iodine. In this system, molecular oxygen in the air acted as a terminal oxidant to regenerate molecular iodine. A mechanistic study was also perfor...

Zusammenfassung:A metal-free photo-oxidative intermolecular C–H/C–H coupling reaction of thiophenes is demonstrated with carbonyls using a catalytic amount of molecular iodine. In this system, molecular oxygen in the air acted as a terminal oxidant to regenerate molecular iodine. A mechanistic study was also performed.
