A ruthenium porphyrin catalyst with styrene side chains was incorporated into a highly cross‐linked polymer by co‐polymerization with ethylene glycol dimethacrylate in the presence of a chloroform porogen. Oxidation reactions catalyzed by the resulting polymer were accelerated when perfluoromethylcyclohexane (PFMC) was used as a co‐solvent. Moreover, the PFMC co‐solvent was found to change the substrate selectivity of the catalytic reactions. Both effects could be explained by a PFMC‐induced partitioning of substrates and oxidant into the polymeric, catalyst containing matrix.
