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.
