摘要：

A novel binuclear Fe(III) complex [Fe(III)(BPMP)Cl(mu-O)Fe(III)Cl-3] (1) was prepared from the reaction between (bis(2-pyridylmethyl)-1,4-piperazine) and [Fe(OH2)(6)]Cl-3, in acetonitrile. The title compound was characterized by spectroscopic, electrochemical and X-ray crystallography analysis. The catalytic activity of the complex was evaluated through cyclohexane oxidation, using hydrogen peroxide as the terminal oxidant. Reaction products were identified by gas chromatography. Conversions up to 19.2% were observed (12.6% and 6.6% yields for cyclohexanol and cyclohexanone, respectively). The catalytic activity exhibited by 1 suggests that it can be considered as a functional biomimetic analog to methane monooxygenase. (c) 2005 Elsevier Inc. All rights reserved.
