这里报道的是一种光催化策略的化学选择性脱羧氧化的羧酸使用Ce(III)催化剂和O2作为氧化剂。通过简单地改变所用的碱,我们证明了反应的选择性可以被引导到有利于氢过氧化物或羰基化合物,每一类产物都以良好到优异的产率和高选择性获得。值得注意的是,有价值的酮、醛和过氧化物直接由容易获得的羧酸生产而没有额外的步骤。
Reported here is a photocatalytic strategy for the chemoselective decarboxylative oxygenation of carboxylic acids using Ce(III) catalysts and O2 as the oxidant. By simply changing the base employed, we demonstrate that the selectivity of the reaction can be channeled to favor hydroperoxides or carbonyls, with each class of products obtained in good to excellent yields and high selectivity. Notably, valuable ketones, aldehydes, and peroxides are produced directly from readily available carboxylic acid without additional steps.
