通过四溴二氮杂卟啉的交叉偶联反应合成了六均铁-5,15-二氮杂卟啉。使用氯铁(III)六均三甲基-5,15-二氮杂卟啉作为环辛烷氧化催化剂表现出高性能，总TON高达731。在β位引入大基团通过形成μ-氧二聚体防止了催化剂失活。
Iron hexamesityl-5,15-diazaporphyrin was synthesized through the cross-coupling reaction of tetrabromodiazaporphyrin. The use of chloroiron(III) hexamesityl-5,15-diazaporphyrin as a catalyst for oxidation of cyclooctane showed high performance with a total TON up to 731. The introduction of bulky mesityl groups at β-positions prevented the catalyst deactivation via formation of a μ-oxo dimer.
