An iron-catalyzed oxidative esterification reaction between unactivated C(sp3)–H bonds from symmetric and asymmetric ethers and carboxylic acids using di-tert-butyl peroxide (DTBP) as the oxidant via a crossdehydrogenativecoupling (CDC) reaction was established, which tolerates a wide range of cyclic ether substrates to react with aromatic acids and phenylacetic acid, providing an efficient method
