Bis(acetylacetonato)copper(II) catalyzed oxidative cross-dehydrogenative coupling (CDC) for the synthesis of α-acyloxy ethers through direct activation of α-C(sp3)–H bond of cyclic ether

Abstract A bis(acetylacetonato)copper(II)catalyzed convenient protocol has been developed for the synthesis of α -acyloxy ethers via cross-dehydrogenative coupling (CDC) using tertiary -butylhydroperoxide (TBHP) as the oxidant. A radical mechanism is suggested for the reaction.
