18 O 2 isotopic labeling studies show that O 2 is able to accomplish the decarboxylation of saturated carboxylic acids through a previously unexplored pathway with TiO 2 as a photocatalyst. In their Full Paper on page 11859 ff. , J. Zhao, W. Ma et al. describe the two major tandem steps of this reaction. In the first step the initial acid is oxidized to an active α‐keto acid intermediate, and in the second step this α‐keto acid is decarboxylated to a shorter‐chain acid with the release of one CO 2 molecule.
