Abstract

Today, the development of porous catalysts for catalytic purposes is being targeted. Herein, this goal was pursued by using the porous substrate of the metal-organic frameworks (MOFs). First, MIL-88B(Fe₂/Co)-TPA-Cu(OAc)₂ as a new catalyst containing copper complex based on Fe and Co-based bimetallic-MOFs was synthesized by using back-to-back solvothermal and reflux methods. The structure of the catalyst was investigated and proved using different methods such as FT-IR, XRD, SEM, EDX, Elemental mapping, XPS, BET/BJH and TGA/DTG. The catalytic activity of the target structure was studied in the preparation of new phenylnicotinonitriles. The results of various investigations showed that MIL-88B(Fe₂/Co)-TPA-Cu(OAc)₂ has good activity in the synthesis of phenylnicotinonitriles and performs these reactions in green and mild conditions. The last step of synthesis has proceeded via a cooperative vinylogous anomeric based oxidation. The structure of the synthesized compounds was identified and confirmed using melting point, FT-IR, ¹H-NMR and ¹³C-NMR techniques. The recyclability of the catalyst was also investigated and good results were obtained. The mentioned properties of this prepared catalyst make it a suitable porous catalyst.
