Fluorinated solvent-assisted photocatalytic aerobic oxidative amidation of alcohols via visible-light-mediated HKUST-1/Cs-POMoW catalysis

Abstract

Considering the irreplaceable importance of photocatalytic functionalization reactions and the widespread attention paid to the use of metal-organic frameworks, especially their modified variants for this purpose in recent years, different...

Elucidating Structural Stability, Bandgap, and Photocatalytic Hydrogen Evolution of (H2O/DMF)@HKUST‐1 Host‐Guest Systems

“…Figure 4a depicts the UV‐Vis spectra of DMF@HKUST‐1 and H 2 O@HKUST‐1 ; we observed two absorption bands at ≈300 and ≈750 nm, which are attributed to the electronic transference of the type π→Cu, and Cu low‐spin →Cu high‐spin , respectively [42] . Also, we calculated the bandgap value using the Tauc plots (Figure 5b) and the following equation: $$$\vcenter{\openup.5em\halign{$\displaystyle{#}$\cr {\left(F\right(R\left)hv\right)}^{n}=A(hv-Eg)\hfill\cr}}$$$ …”

“…and � 750 nm, which are attributed to the electronic transference of the type π!Cu, and Cu low-spin !Cu high-spin , respectively. [42] Also, we calculated the bandgap value using the Tauc plots (Figure 5b) and the following equation:…”

Confined-based catalyst investigation through the comparative functionalization and defunctionalization of Zr-MOF

“…30,31 It has been concluded that environmentally-friendly MOFs and eco-friendly strategies based on sustainable building blocks are ideal for the intended purpose. [32][33][34][35][36][37] Frameworks based on terephthalic acid and 2-aminoterephthalic acid and iron, aluminium, chromium, cerium and zirconium clusters are essential in catalytic studies due to their unparalleled stability. [38][39][40][41][42][43][44][45][46] Recently, structures based on zirconium and terephthalic acid-based ligands, namely the UiO-66 family, have captured much attention in various applications.…”

Acid Catalyzed Stereocontrolled Ferrier-Type Glycosylation Assisted by Perfluorinated Solvent

“…Perfluorinated hydrocarbons displaying low chemical activity, low toxicity and low miscibility with common organic solvents have been recognized as a class of useful reaction mediums in various research fields [ 26 , 27 ], particularly in molecular-oxygen-involved aerobic oxidation reactions [ 28 , 29 , 30 , 31 , 32 , 33 , 34 ]. Wide application potential is also found in biphase catalysis by virtue of their unique physical properties [ 35 , 36 ].…”
