Copper corrole complex was firstly used as catalyst for oxidative esterification of un-reactive C(sp3)-H bond of cyclic ether and carboxylic acid via cross dehydrogenative coupling (CDC) reaction using di-tert-butyl peroxide (DTBP) as oxidant. A wide range of carboxylic acids can react with cyclic ether with good to excellent yields, showing copper corrole is a new kind of promising catalyst for CDC reaction. Under gram-level test, the turnover number (TON) may achieve 8400 with 84% yield at only 0.01% catalyst loading, demonstrating its practical uses.
