Abstract: A novel method for synthesis of substitutedμ-oxo-bis[tetraphenyl porphyrinatoiron]compounds([TRPPFe]2O) based on the reaction among free base porphyrins(TRPPH2),FeSO4·7H2O and H2O in one pot was proposed and investigated.Four kinds of[TRPPFe]2O were synthesized by this novel synthetic method,and their structures were characterized by elemental analysis,infrared spectra and UV-vis spectroscopy.The reaction conditions,including the effect of different iron salts on the formation of[TRPPFe]2O,the reaction time between FeSO4·7H2O and TRPPH2,the molar ratio of FeSO4·7H2O/TRPPH2 as well as the volume ratio of H2O/DMF,were investigated.The [TRPPFe]2O yield of 93%-98%could be obtained under the following optimal conditions:the reaction time of FeSO4·7H2O with TRPPH2 was about 10 h,the molar ratio of FeSO4·7H2O/TRPPH2 about 5:1,and the volume ratio of H2O/DMF exceeded 2:1.Further research indicated that only TRPPFeCl were formed once FeSO4·7H2O was replaced by FeCl2·4H2O,the reason of which might be that halogen ions in iron salts interfered the formation of [TRPPFe]2O,suggesting that halogen ions should be avoided in this novel synthetic method.
