Conversion of CO₂ to epoxides or oxazolidinones enabled by a Cu^I/Cu^II-organic framework bearing a tri-functional linker

Abstract

Metal-Organic Frameworks (MOFs) as effective catalysts can contribute to the effective green conversion of CO2. However, more studies have focused on the conversion of epoxides to cyclic carbonate systems, but...

Nanocage-based {In2Tm2}-organic framework for efficiently catalyzing the cycloaddition reaction of CO2 with epoxides and Knoevenagel condensation

“…4. 67–71 Firstly, the cycloaddition reaction began with the O atom of epoxide being activated by the Lewis acidic In 3+ and Tm 3+ sites to form In/Tm-epoxide adducts, resulting in the instability of the ternary rings. Subsequently, the Br − ions released from the co-catalyst of n -Bu 4 NBr launched an affinity attack on the C atom with less steric hindrance to produce the main intermediates of alkylcarbonate anions, whose O − atoms served as a nucleophilic reagent to react with CO 2 in the pores, generating the carbonate ester as the secondary intermediate.…”

Thermocatalytic Conversion of CO2 to Valuable Products Activated by Noble‐Metal‐Free Metal‐Organic Frameworks

“…For example, tedizolid phosphate is an efficient medicine against Gram positive bacteria, and has been proved have the advantages of low incidence of drug resistance and few adverse reactions, which is very friendly to elderly and children; Linezolid can inhibit the protein synthesis of bacterial and has good compatibility with other drugs, hence it is widely used to treat bacterial infections of the skin. Typically, there are three methods to synthesize oxazolidinones (Figure 2): Cycloaddition of CO 2 and aziridines, carboxylation cyclization of propargyl amines and CO 2 , and synthesis of oxazolidinones by three‐components reaction [83, 84] …”

Fabrication of a Cu(i)-carboxylate metal–organic framework by reduction of metal nodes for an azide–alkyne “click” reaction

“…Functionalization of metal-organic frameworks (MOFs) with Cu(I) sites holds significant promise for various applications including adsorption, separation, catalysis, and sensing. [13][14][15][16][17][18] However, according to the above HSAB theory, Cu (I)-MOFs are usually fabricated using ligands with pyridyl N-or sulfhydryl S-centers. Although carboxylate-based MOFs constitute the overwhelming majority, Cu(I)-MOFs fabricated with carboxylate-based ligands are expected to exhibit thermal stability and have broad catalytic applications.…”
