Abstract (EN): Two salen derivatives bearing a metoxi-group in the phenyl ring (positon 3) and the corresponding Mn(III) complexes free and inside zeolite cavities have been prepared. The new materials were characterized by several techniques: ICP-AES, XPS, X-ray diffraction, TG-DSC, N-2 adorption and FT-IR. Both complexes catalyzed the cyclohexene oxidation with TBHP, with low conversions, primarily to allylic oxidation products. Evidence supports a radical autoxidation chain mechanism, with the complexes functioning to decompose intermediate alkylhydroperoxides.
