Diferric Oxo-Bridged Complexes of a Polydentate Aminopyridyl Ligand: Synthesis, Structure and Catalytic Reactivity

Abstract

The catalytic reactivity of a group of diferric oxo-bridged complexes (1-3) of a tetradentate ligand (bpmen = N,N'-dimethyl-N,N'-bis(2-pyridylmethyl)-1,2-diaminoethane) toward alkane hydroxylation has been evaluated. Among the three complexes, the μ-oxo diiron(III) complex [Fe(bpmen)(μ-O)FeCl3] (1) has been synthesized for the first time. The complex 1 has been characterized by spectroscopic analysis and X-ray crystallography. At room temperature, the μ-oxo diiron(III) complexes 1-3 have been found to be useful catalysts in hydroxylation of alkanes with m-chloroperbenzoic acid as oxidant. [Fe(bpmen)(μ-O)FeCl3] (1) has been found to be the most active catalyst. Moreover, the catalytic ability of the complexes in the oxidation of alcohols to ketones with hydrogen peroxide at room temperature has also been investigated.
