Manganese(III) tetrapyridylporphyrin-chloromethylated MIL-101 hybrid material: A highly active catalyst for oxidation of hydrocarbons

• Novel hybrid material Mn(TPyP)OAc/CM-MIL-101 was synthesized.
• This catalyst was characterized by FT-IR, SEM, UV–Vis, BET, XRD and ICP techniques.
• The catalytic activity was investigated in epoxidation of alkenes and hydroxylation of alkanes.
• This heterogeneous catalyst was active, efficient and reusable.

In the present work, tetra(4-pyridyl)porphyrinatomanganese(III) acetate, Mn(TPyP)OAc, was covalently attached to chloromethylated MIL-101, CM-MIL-101, and a new hybrid material was prepared. The Mn(TPyP)OAc/CM-MIL-101 hybrid catalyst was characterized by FT-IR and diffuse reflectance UV–Vis spectroscopic methods, inductively coupled plasma (ICP), X-ray diffraction (XRD), BET and scanning electron microscopy (SEM) methods. This heterogenized catalyst was applied in epoxidation of alkenes and hydroxylation of alkanes with sodium periodate at room temperature. The catalyst reusability was also investigated and no significant metal leaching and decreasing of the catalyst activity were detected.
