Abstract: 
Dinuclear iron peroxido complexes are important intermediates for selective oxidation reactions. A detailed kinetic study of the reaction of benzoyl chloride (BzCl) with a dinuclear iron non-heme cis end-on peroxido complex with the ligand EtHPTB (N,N,N ',N '-tetrakis[(N-ethyl-2-benzimidazolyl)methyl]-2-hydroxy-1,3-diamino-propane) had been performed. The starting complex, the iron peroxido complex, can be obtained either by reaction of the iron(II) complex with O-2 or instead, applying the corresponding iron(III) complex together with hydrogen peroxide. Using low temperature stopped-flow measurements allowed to obtain activation parameters and in combination with a Hammet plot it was possible to postulate a mechanism for the formation of a perbenzoate complex prior to its decomposition. Furthermore, the direct reaction of the dinuclear iron(III) EtHPTB complex with peracetic acid was analyzed. Additionally, in comparison a mononuclear non-heme iron complex with the ligand bztpen (N-benzyl-N,N ',N '-tris(2-pyridylmethyl)ethane-1,2-diamine) was investigated as well.
