Oxygenation of alkenes is one of the most straightforward routes for the construction of carbonyl compounds. Wacker oxidation provides a broadly useful strategy to convert the mineral oil into higher value-added carbonyl chemicals. However, the conventional Wacker chemistry remains problematic, such as the poor activity for internal alkenes, the lack of anti-Markovnikov regioselectivity, and the high
烯烃的氧化是构建羰基化合物最直接的途径之一。瓦克氧化提供了一种广泛有用的策略,可以将矿物油转化为更高附加值的羰基化学品。然而,传统的瓦克化学仍然存在问题,例如内烯烃的活性差,缺乏抗马尔科夫尼科夫区域选择性,以及贵金属催化剂和化学计量氧化剂导致的高成本和化学浪费。在这里,我们描述了一种前所未有的β-烷基苯乙烯及其衍生物在无外部氧化剂条件下与水脱氢氧化,利用光催化和质子还原催化的协同效应来解决这些挑战。
