英文摘要	A Co-II/CF3COOH (TFA)-catalyzed oxidative esterification of aldehydes and alkanols by using tBuOOH as an oxidant is reported. A mechanistic investigation indicated that the oxidation reaction proceeded through the formation of a Co-III-OCH(OMe)R complex, followed by H-atom abstraction by an in-situ-generated tBuO(center dot) radical. The former kinetic step was thought to be the selectivity-determining step. Moreover, the strong acidity and TFA proton were beneficial for both the dehydrative formation of the Co-III-OCH(OMe) R complex and the redox properties of the cobalt atom, thereby offering high efficiency for the target oxidative cross-coupling reaction.
