“…During the catalytic tests utilizing MOFs, two types of Knoevenagel condensation compounds, namely, (E) and (Z) ethyl 2-cyano-3-(4-nitrophenyl) acrylate, were produced. The product was con rmed by 1 H, 13 C, 1 H- 13 C HSQC, and HMBC NMR spectroscopy. The probe was tuned, matched and shimmed before the images were acquired.…”

“…1 H and13 C NMR spectral data for ethyl 2-cyano-3-(4-nitrophenyl)acrylate(1) and methyl-2-cyano-3-(4-nitrophenyl)acrylate (2) in CDCl 3 (500 MHz)The use of certain MOFs resulted in the formation of Z/E isomers of ethyl-2-cyano-3(4-nitrophenyl) acrylate, with a selectivity ratio of 15/85. However, the behavior of MOF-Cr-NH 2 was distinct from that of other MOFs, as it produced both Z/E methyl-2-cyano-3(4-nitrophenyl) acrylate (selectivity ratio of 7/50) and (E)-ethyl-2-cyano-3(4-nitrophenyl) acrylate (selectivity ratio of 42).…”

Metal-organic frameworks (MOFs) are porous materials composed of metal ions, clusters and organic ligands. Due to their outstanding chemical, thermal, and solvent stability, as well as numerous unsaturated metal sites, they have proven to be useful catalysts. In this study, MOFs were synthesized using hydrothermal methods with terephthalic acid and Ca, Mg, Al, and Cr nitrates. Subsequently, the MOFs were functionalized with diethylamine. The formation of MOF-Al and MOF-Cr structures was confirmed through characterization by XRD, FT-IR, and CHN analyses, while MOF-Ca and MOF-Mg could not be detected. SEM images revealed the particle size and morphology of the particles, which ranged between 0.2 and 1 mm. TGA/DTA curves revealed that the functionalized MOFs were the most thermally stable. Textural analysis by N2 adsorption/desorption showed that MOF-Cr and MOF-Cr-NH2 had high BET area values of 1,769.67 and 998.22 m2g− 1, respectively. The MOFs were employed as catalysts in Knoevenagel condensation reactions to synthesize (E)-ethyl 2-cyano-3-phenylacrylate and (E)-methyl 2-cyano-3-phenylacrylate, indicating their potential for reactions requiring acidic or basic sites.

“…Starting from the plastic waste, chemical recycling may proceed via different processes, including glycolysis, hydrolysis, and methanolysis-hydrolysis being the most interesting one for MOF synthesis since it results directly in terephthalic acid [39]. In the last years, several reports can be found on the use of PET as the ligand source for the sustainable production of different MOFs [40][41][42]. Of particular interest is the possibility of producing the TPA (also known as H 2 BDC) via PET hydrolysis and simultaneously form the MOF in a one-pot reaction, as reported by some authors [43,44].…”

In the last decade, MOFs have been proposed as precursors of functional porous carbons with enhanced catalytic performances by comparison with other traditional carbonaceous catalysts. This area is rapidly growing mainly because of the great structural diversity of MOFs offering almost infinite possibilities. MOFs can be considered as ideal platforms to prepare porous carbons with highly dispersed metallic species or even single-metal atoms under strictly controlled thermal conditions. This review briefly summarizes synthetic strategies to prepare MOFs and MOF-derived porous carbons. The main focus relies on the application of the MOF-derived porous carbons to fine chemical synthesis. Among the most explored reactions, the oxidation and reduction reactions are highlighted, although some examples of coupling and multicomponent reactions are also presented. However, the application of this type of catalyst in the green synthesis of biologically active heterocyclic compounds through cascade reactions is still a challenge.
