Among them, diiron porphyrin dimers containing μ-oxo bridge are particularly interesting, as they exhibit efficient oxygen atom transfer capability. In this study, we aim to develop a simple and efficient one-pot synthesis method for μ-oxo bridged bis(tert-butylphenyl)-substituted diiron(III) dimer porphyrin.Experimental approach:The synthesis will start with the reaction of iron(III) chloride with tert-butylphenyl-substituted porphyrin in hot pyridine. The reaction will be carried out under inert atmosphere with reflux for 24 hours. The resulting iron porphyrin complex will then be treated with sodium hydroxide in methanol to form the diiron(III) dimer. Finally, μ-oxo bridging will be achieved by air oxidation, and the product will be isolated by column chromatography.Expected outcomes:We anticipate to obtain high yield of the μ-oxo bridged bis(tert-butylphenyl)-substituted diiron(III) dimer porphyrin using this one-pot synthesis method. The product will be characterized by various spectroscopic techniques such as UV-vis absorption, IR, and NMR spectroscopy. We will also evaluate the oxygen atom transfer capability of the synthesized diiron(III) dimer using a model substrate. Conclusion:In summary, the one-pot synthesis of μ-oxo bridged bis(tert-butylphenyl)-substituted diiron(III) dimer porphyrin will be carried out by the reaction of iron(III) chloride with tert-butylphenyl-substituted porphyrin followed by sodium hydroxide treatment and air oxidation. This method will offer a 精品文档---下载后可任意编辑simple and efficient route for the synthesis of diiron porphyrin dimers with μ-oxo bridge, which could have potential applications in various fields such as catalysis and energy conversion.
