A zirconium metal-organic framework catalyst was synthesized and investigated in the ring opening of epoxides with nucleophiles such as amines, alcohols, and thiophenol. For comparative study, Cu and Zn metal-organic framework catalysts were prepared. The zirconium based porous metal-organic framework catalyst was characterized by powder X-ray diffraction, nitrogen adsorption, scanning electron microscopy, thermo gravimetric analysis, and Fourier transform infrared spectroscopic techniques. Application of these catalysts was also investigated in the nucleophilic addition of amines/thiophenol with activated olefins. Among the catalysts investigated in this study, zirconium metal-organic framework catalysts exhibited the highest activity in these reactions. In this study, systematic assessment of the catalytic activity of zirconium metal-organic framework for a wide range of aromatic and heterocyclic compounds is shown under one umbrella. Catalysts can be easily recovered and reused with negligible loss in the catalytic activity.
