The selectivity of hydroxylation of the distal rings of 4‐phenylbenzoic acid, 4‐phenylsalicylic acid, and 5‐phenylsalicylic acid were determined using partial TiO2‐mediated photocatalytic degradation and photo‐Fenton conditions. This separation of the binding site from the phenyl group being hydroxylated allows a less‐biased evaluation. The hydroxylation regiochemistry behaves as qualitatively expected
