    • Typical Procedure for the Fe(III)-Mediated Synthesis of Dioxoporphyrins Zn2 A mixture of Znla (100 mg, 0.19 mmol, 1.0 equiv) and FeCl36H2O (513 mg, 10 equiv) was stirred in DMF (20 mL) in air at 130 °C for 5 h. After cooling to r.t, the reaction mixture was diluted with CH2Cl2 (20 mL) and washed with H 2O three times. The organic layer was passed through dry SiO 2 and evaporated to dryness. The resulting solid was crystallized from CH2Cl2-MeOH or purified by flash column chromatography (SiO2, 300-400 mesh, PE-EtOAC 4:1) to produce the desired dioxoporphyrin Zn2a (90 mg, 85% yield, Characterization Data for Selected Representative Compounds Dioxoporphyrin Zn2a 1H NMR (300 MHz, acetone-d6, δ, 6.28-6.31 (m, 4 H, β-H, 6.87-6.90 (m, 4 H, β-H, 7.33 (d, J=3.6 Hz, 4 H, PhH, 7.40-7.42 (m, 6 H, PhH, MS MALDI
