Carboxamide functionality grafted entangled Co(ii) framework as a unique hydrogen-bond-donor catalyst in solvent-free tandem deacetalization-Knoevenagel condensation with pore-fitting-mediated size-selectivity

Abstract

Concerning environmentally benign catalysis with reduced chemical usage, less energy consumption, and waste minimization, metal-organic frameworks (MOFs) with spatially isolated task-specific functionalities not only execute atom-economic important reactions but also...

Multifunctional Metal‐Organic Frameworks as Catalysts for Tandem Reactions

“…Some MOFs composites as efficient catalysts for one-pot tandem reactions that unclassified within aforementioned category, will be discussed in this section. For instance, formylfunctionalized Co(II) MOF, [32] MOF-on-MOF composites, [33] and CsCu 2 I 3 -doped PCN-222 ( Fe) [34] both delivered excellent catalytic performance for the classical tandem descaling-Knoevenagel condensation reaction. Moreover, carbon-based materials are extensively utilized as heterogeneous catalysts owing to their robust chemical and mechanical stability, varied structures, and cost-effectiveness.…”

Thiol and thioether-based metal–organic frameworks: synthesis, structure, and multifaceted applications

“…Crystalline and porous compounds formed by the coordination interaction between metal ions or clusters with organic ligands are called metal–organic frameworks (MOFs). 1–5 From the time of their discovery in the 1990s, MOFs have received the utmost attention because of their extensive potential applications in fields like gas adsorption and separation, 6,7 heavy metal adsorption, 8,9 catalysis, 10–15 sensing, 16–18 drug delivery, 19,20 electrical conductivity, 21 proton conductivity, 22 photocatalysis, 23 materials with magnetic properties, 24,25 and optical devices 26,27 etc . The root cause of their diverse applications is excellent stability, 28 high surface areas, 29 ordered porosity 30 and fascinating tuneable functionalities.…”
