We report the photochemical carboxylation of o-phenylenedimamine in the absence of a base and an electron donor under an atmosphere of CO2, which afforded 2,3-diaminobenzoic acid (DBA) in 28% synthetic yield and 0.22% quantum yield (Φ(%)). The synthetic yield of DBA in this reaction increased to 58% (Φ(%) = 0.47) in the presence of Fe(II). The photochemical reaction described in this work provides an effective strategy to use light as the driving force for the direct carboxylation of organic molecules by CO2.

The Front Cover shows that the results presented in this paper arise from the interplay of inorganic clusters (depicted by the pot) and organic substituents (symbolized by the flower), which leads to remarkable changes in the redox properties of the cluster cores. Specifically, methylation of the cluster cores enhances their electron‐accepting properties.

Methylation of the molybdenum sulfide cluster unit [Mo 6 S 8 (PEt 3 ) 6 ] (1) with CH 3 OTf resulted in the formation of mono-and dimethylated cluster units, [Mo 6 S 8-x (SCH 3 ) x -(PEt 3 ) 6 ]OTf·yCH 2 Cl 2 {[2]OTf·0.5CH 2 Cl 2 (x = 1, y = 0.5) and [a]
