Oxygenation reactions with molecular oxygen (O2) as the oxygen source provides a green and straightforward strategy for the construction of O‐containing compounds. Demonstrated here is a novel N‐heterocyclic carbene (NHC) catalyzed oxidative transformation of simple and readily available organic halides into valuable esters through the incorporation of O‐atoms from O2. Mechanistic studies prove that
以分子氧(O 2)为氧源的加氧反应为构建含O化合物提供了绿色而直接的策略。这里展示的是一种新颖的N杂环卡宾(NHC)通过将O 2中的O原子并入,将简单易用的有机卤化物催化氧化转化为有价值的酯的方法。机理研究证明,原位产生的脱氧Breslow中间体被氧化为Breslow中间体,通过该氧化方案进一步转化。该方法拓宽了NHC催化领域,并促进了与O 2的氧化反应。
