Catalytic oxidation of concentrated orange oil phase by synthetic metallic complexes biomimetic to MMO enzyme.

Background: This paper reports the catalytic oxidation of the concentrated orange oil phase using the complexes [Fe(III)(BMPP)Cl(micro-O)Fe(III)Cl(3)], [Cu(II)(BTMEA)(2)Cl]Cl and [Co(II)(BMPP)]Cl(2) biomimetic to methane monooxygenase enzyme as catalysts and hydrogen peroxide as oxidant.

Results: The reaction products of oil oxidation, mainly nootkatone, were identified by gas chromatography/mass spectrometry. A screening of catalysts was performed through a full 2(3) experimental design, varying the temperature from 30 to 70 degrees C, the catalyst concentration from 7.

Catalytic oxidation of cyclohexane by a binuclear Fe(III) complex biomimetic to methane monooxygenase.

A novel binuclear Fe(III) complex [Fe(III)(BPMP)Cl(mu-O)Fe(III)Cl3] (1) was prepared from the reaction between (bis(2-pyridylmethyl)-1,4-piperazine) and [Fe(OH2)6]Cl3, 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.
