| Abstract: | A new tetrapyridyl ligand (BDPEA) and the corresponding di-iron(III) μ-oxo complex were synthesized. The iron complex structure, determined by X-ray crystallography, exhibited the dinuclear core [Fe2III(BDPEA)2(μ-O)(NO3)2](NO3)2 (1). With monopersulfate as oxidant, this complex catalyzed the conversion of 2,4,6-trichlorophenol and catechol, with a better activity and an enhanced life-time compared to the previously reported complex [FeIII(BDPMA)](NO3)3 (2) (BDPMA: bis[di(2-pyridyl)methyl]amine) which contained two fragile benzylic C–H bonds on the tetrapyridyl ligand. |
