Post-synthetic modified MOF for Sonogashira cross-coupling and Knoevenagel condensation reactions

Ruthenium Complexes Immobilized on an Azolium Based Metal Organic Framework for Highly Efficient Conversion of CO2 into Formic Acid

“…Two signals centered at the binding energies of 1022.3 eV and 1045.3 eV in the as‐synthesized MOF corresponded to Zn 3p 3/2 and Zn 3p 1/2 peaks, respectively, as also observed in the case of Ru1‐NHC‐MOF, Ru2‐NHC‐MOF and Ru3‐NHC‐MOF catalysts. The two characteristic binding energies were features of divalent zinc(II) cation, which also proved that the zinc(II) cations coordinated with the carboxylic acid groups for the successful synthesis of MOF . With respect to XPS spectra of Ru, however, there was a slight difference in three Ru‐NHC‐MOF catalysts.…”

“…Particularly, the FT‐IR spectrum of organic ligand exhibited one sharp peak at 1175 cm −1 , which was assigned to the C−H band of the C2 position of the imidazolium ring . Whereas this characteristic band declined significantly in the FT‐IR spectra of all catalysts, therefore reasonably supporting the coordination of the Ru species to the carbenic carbon of the imidazolium moieties …”

Designing of Ultrafine PdNPs Immobilized Pyridinic‐NDoped Carbon and Evaluation of its Catalytic Potential for Konevenagel Condensation, Synthesis of 4H‐pyran Derivatives and Nitroreduction

“…Benzylidenemalononitrile (BMN) derivatives act as intermediates for the generation of many biologically important molecules such as enzyme inhibitors, carbohydrates and heterocycles . Already reported method for the Knoevenagel condensation by palladium suffers from certain limitations such as less yield, longer reaction time and tedious workup procedure . 4 H ‐pyran derivatives and its analogues heterocyclic compounds are mainly an important class of oxygen‐containing skeleton that constitute the core motif of various natural products .…”

Solid-Supported Palladium Catalysts in Sonogashira Reactions: Recent Developments

“…This modified MOF showed a high density and uniform distribution of the active sites and catalyzed the Sonogashira reaction between aryl iodides, bromides or chlorides and arylacetylenes, using potassium carbonate as base and DMF as solvent at 100 • C, retaining its catalytic activity for at least four cycles without losing its structural integrity [124]. Similarly, dicarboxylic acid palladium complex 73 ( Figure 22) has been assembled with zinc nitrate forming a mesoporous palladium(II) coordination polymer Pd(II)-CP.…”
