An efficient cyclic ether benzoxylation was achieved by using iron porphyrin as the catalyst and di-tert-butyl peroxide oxidant. The benzoic acid substrates bearing electron donating or withdrawing groups could react with cyclic ether smoothly to afford the desired products. It was found iron porphyrin catalyzed oxidative C (sp3)-H activating esterification had the advantage of short reaction time and low catalyst loading. The reaction had been proved to proceed via a radical process.

铁卟啉催化的C(SP 3)-H活化,通过环醚与芳酸的交叉脱氢偶联形成C O键

通过使用卟啉铁作为催化剂和过氧化二叔丁基氧化剂可实现有效的环醚苯氧化。带有给电子或吸电子基团的苯甲酸底物可以与环醚平稳反应,得到所需的产物。发现铁卟啉催化的氧化的C(sp 3)-H活化酯化反应具有反应时间短,催化剂负载量低的优点。已经证明该反应是通过自由基过程进行的。
