Synthesis and application of [Zr-UiO-66-PDC-SO₃H]Cl MOFs to the preparation of dicyanomethylene pyridines via chemical and electrochemical methods.

ABSTRACT: A metal-organic framework (MOF) with sulfonic acid tags as a novel mesoporous catalyst was synthesized. The precursor of Zr-UiO-66-PDC was synthesized both via chemical and electrochemical methods. Then, zirconium-based mesoporous metal-organic framework [Zr-UiO-66-PDC-SO₃H]Cl was prepared by reaction of Zr-UiO-66-PDC and SO₃HCl. The structure of [Zr-UiO-66-PDC-SO₃H]Cl was confirmed by FT-IR, PXRD, FE-SEM, TEM, BET, EDX, and Mapping analysis. This mesoporous [Zr-UiO-66-PDC-SO₃H]Cl was successfully applied for the synthesis of dicyanomethylene pyridine derivatives via condensation of various aldehyde, 2-aminoprop-1-ene-1,1,3-tricarbonitrile and malononitrile. At the electrochemical section, a green electrochemical method has successfully employed
