Epoxidation of Olefins in the Presence of Molybdenum Catalysts based on Porous Aromatic Frameworks

Yarchak, V. A. / Kulikov, L. A. / Maximov, A. L. / Karakhanov, E. A.

A porous aromatic framework, namely PAF-30, was structurally modified by the introduction of complexing groups based on dipyridylamine, dipicolylamine, and acetylacetone. The materials synthesized in this manner were used as supports of molybdenum catalysts for epoxidation: PAF-30-dpa-Mo, PAF-30-dpcl-Mo, and PAF-30-AA-Mo. All the materials were examined by various analytic methods, such as IR spectroscopy, low-temperature nitrogen adsorption/desorption, X-ray photoelectron spectroscopy, elemental analysis, and transmission electron microscopy. The catalytic activity was tested in epoxidation of cyclohexene, 1-hexene, 1-octene, and styrene. The reusability of the catalysts was assessed using the case of cyclohexene epoxidation.
