“…Zhang et al. reported the use of palladium nanoparticles supported on nanocrystals of MOF based on scandium . They found interesting catalytic activities for Suzuki–Miyaura cross couplings, but their catalyst seems to lack robustness and was only synthesized on a small scale in a microwave reactor vial.…”

Heterogeneous Catalysis by Covalent Organic Frameworks (COF): Pd(OAc)₂@COF‐300 in Cross‐Coupling Reactions

COF‐300, an imine‐linked, crystalline, and microporous covalent organic framework, modified by coordination of Pd(OAc)2 to its walls, afforded a hybrid material, Pd(OAc)2@COF‐300, which was used as an efficient heterogeneous catalyst for cross‐coupling reactions. This material showed excellent catalytic activity for the phosphine‐free Suzuki–Miyaura, Heck, and Sonogashira cross‐coupling reactions with low palladium loadings (0.1 mol % Pd). X‐ray photoelectron spectroscopy analysis of the catalyst after the reaction showed that PdII is converted to Pd0, which is trapped within the COFs nanopores. This was confirmed by high‐resolution transmission electron microscopy. Moreover, promising results were obtained using Pd(OAc)2@COF‐300 under continuous‐flow conditions for a Suzuki–Miyaura cross‐coupling reaction.

“…When assembled at the nanoscale, they are called nanoMOFs. Analogously to other classes of nanoparticles, nanoMOFs show size‐dependent properties (e.g., different adsorption kinetics or better dispersibility compared with their bulk analogues),1 which can be exploited in numerous practical applications, including traditional storage4 and catalysis,5, 6 and in newer areas such as sensors,7 functional membranes and thin‐films,8, 9 and in biomedical applications such as drug‐delivery,10–12 NO absorption,13, 14 and contrast agents 15. The ever‐increasing interest in nanoMOFs (and in their bulk analogues) should ultimately lead to their widespread production and use.…”

Metal–organic frameworks (MOFs) are among the most attractive porous materials available today. They have garnered much attention for their potential utility in many different areas such as gas storage, separation, catalysis, and biomedicine. However, very little is known about the possible health or environmental risks of these materials. Here, the results of toxicity studies on sixteen representative uncoated MOF nanoparticles (nanoMOFs), which were assessed for cytotoxicity to HepG2 and MCF7 cells in vitro, and for toxicity to zebrafish embryos in vivo, are reported. Interestingly, there is a strong correlation between their in vitro toxicity and their in vivo toxicity. NanoMOFs were ranked according to their respective in vivo toxicity (in terms of the amount and severity of phenotypic changes observed in the treated zebrafish embryos), which varied widely. Altogether these results show different levels of toxicity of these materials; however, leaching of solubilized metal ions plays a main role.

“…However, due to their low chemical and thermal stability, these are not applicable for reactions that require severe conditions [3,7,49,50]. MOFs were used as a catalyst or catalyst supports for a diversity of organic transformations including Friedel-Crafts reactions [51][52][53][54][55], Knoevenagel condensation [56][57][58][59][60], aldol condensation [61][62][63], oxidation [64][65][66][67], coupling reactions [68][69][70][71][72][73][74][75], cyano silylation [15,76,77], carbon dioxide fixation [78,79], etc ( Fig. 1).…”

Metal-organic frameworks (MOFs) are an emerging class of porous materials created by the assembly of inorganic connectors and organic linkers. They have potential applications in fields such as gas storage as well as separation, sensing, catalysis, and drug delivery due to its properties such as flexibility, porosity, high surface area and functionality. Among the various synthetic approaches for the preparation of MOFs, solvothermal and microwave-assisted methods are of particular importance, and hence have been used frequently. They have been recently used as heterogeneous catalysts in Friedel-Crafts reactions, condensations reactions, oxidations, coupling reactions, etc. However, owing to the low thermal stability and moisture sensitivity, their catalytic applications are limited. This short review covers recent developments in the synthetic methods employed for the preparation of MOFs as well as their catalytic applications.
