A protocol for solvent-free and additive-free oxidation of primary benzylic C–H bonds with O2 was presented through adjusting the combination of metalloporphyrins and NHPI as binary catalysts to overcome the deficiencies encountered in current oxidation systems. The effects of reaction temperature, porphyrin structure, central metal, catalyst loading and O2 pressure were investigated systematically

Reported here is a photocatalytic strategy for the chemoselective decarboxylative oxygenation of carboxylicacids 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
此处报道的是一种使用 Ce(III) 催化剂和 O 2作为氧化剂的羧酸化学选择性脱羧氧化的光催化策略。通过简单地改变所用的碱,我们证明反应的选择性可以引导到有利于氢过氧化物或羰基化合物,每一类产品都以良好到极好的收率和高选择性获得。值得注意的是,有价值的酮、醛和过氧化物是直接从容易获得的羧酸中生产出来的,无需额外的步骤。
