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.
使用催化量的分子碘,证明了羰基化合物与噻吩的无金属光氧化分子间C–H / C–H偶联反应。在该系统中,空气中的分子氧充当终端氧化剂,以再生分子碘。还进行了机理研究。
