Synthesis of new perfluorinated binaphthyl Mn(III) complexes and epoxidation of styrene in supercritical carbon dioxide

• In this study, new perfluorinated binaphthyl Mn(III) complexes have been synthesized by template effect.
• Mn(III) complexes were characterized by elemental analysis, FT-IR, LC/MS, UV–vis spectroscopy.
• Catalytic activities of the catalysts have been tested in homogeneous asymmetric epoxidation of styrene in both dichloromethane (organic solvent) and supercritical carbon dioxide (scCO2).
• The effect of reaction parameters was investigated in epoxidation of styrene.

In this article, new perfluorinated binaphthyl Mn(III) complexes have been synthesized by template effect. The synthesized complexes were characterized by elemental analysis, FT-IR, LC/MS, UV–vis spectroscopy. After the solubility of the catalysts in scCO2 was observed through the high pressure reactor, catalytic activities of the catalysts have been tested in homogeneous asymmetric epoxidation of styrene in both dichloromethane (organic solvent) and supercritical carbon dioxide (scCO2). In order to determine and compare to complexes, the effect of synthesized catalysts to conversion and selectivity was investigated. Reaction parameters such as; reaction time, solvent type and position of substituents were also assessed during the analysis.
