摘要/Abstract

摘要： 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.
