导向的过渡金属催化不活泼C(sp^3)-H键氧化反应研究进展

Progress in Directed Transition Metal-Catalyzed Oxidation of Inactive C(sp^3)-H Bonds

近年来,过渡金属催化不活泼C(sp3)—H键氧化反应取得重要进展.该领域的研究主要集中在过渡金属催化甲烷选择性氧化,以及过渡金属催化导向基团螯合甲基氧化方面,这些研究成果实现了许多传统氧化方法不能完成的高效选择性转化.重点概述导向基团(肟、噁唑啉、吡啶、酰胺、羧酸、羟基)对促进过渡金属催化氧化C(sp3)—H键的影响,底物的乙酰氧基化、羟基化、羰基化、酯化反应以及催化反应体系和相关机制.

The recent progress in transition metal-catalyzed oxidation of C（sp3）--H bonds has been made. Researches focus on the selective oxidation of methane, as well as the oxidation of methyl groups assisted by chelating directing groups. The researches lead to efficient and highly selective oxidative conversion that are unable to solve by traditional methods. This re- view covers the effect of directing groups （oxime, oxazoline, pyridine, amide, carboxylic acid, and hydroxyl） on promoting oxidation of C（sp3）--H bonds, the formation of acetylation, hydroxylation, carbonylation, esterification, and metal-catalyzed oxidative reaction system and mechanisms.
