A Multifunctional Zirconium-Based Metal-Organic Framework for the One-Pot Tandem Photooxidative Passerini Three-Component Reaction of Alcohols

A porous multifunctional zirconium-based metal-organic framework (MOF) was achieved by combined covalent and dative post synthetic modification (PSM) of the UiO-66-NH2, and characterized by a variety of techniques, including FTIR spectroscopy, powder XRD, N-2 temperature-programmed adsorption/desorption, scanning electron microscopy, thermal gravimetric analysis, inductively coupled plasma atomic emission spectroscopy, and UV/Vis diffuse reflectance spectroscopy. The MOF (Zr-MOF-FePC, PC=2-pyridinecarboxaldehyde) is an active, efficient, and reusable catalyst for the one-pot tandem photooxidative Passerini three-component reaction of alcohols. This is a new type of tandem photocatalyst and cooperative catalyst and was obtained in the course of developing MOFs as versatile heterogeneous catalysts for diverse tandem oxidative multicomponent reactions. This work illustrates the potential of MOFs as multifunctional heterogeneous catalysts for sustainable chemistry.
