Abstract An effective one‐pot method for the conversion of carbon dioxide, ethylene oxide, and amines to 3‐aryl‐2‐oxazolidinones has been developed. This consists two parallel reactions a subsequent cascade reaction between products corresponding reactions. Notably, binary ionic liquids 1‐butyl‐3‐methyl‐imidazolium bromide acetate demonstrate synergistic catalytic effect on this new strategy. 1‐Butyl‐3‐methyl‐imidazolium is essential in owing good nucleophilicity leaving ability bromide,...
Abstract The cooperative effects of cation–anion are elucidated in ionic liquid‐catalyzed reactions aniline with ethylene carbonate and the reaction phenylacetonitrile dimethyl carbonate. Cations liquids activate electrophiles by proton 2‐position imidazolium ring through hydrogen‐bond interaction carbonyl group. catalytic activity follows order 1‐butyl‐3‐methyl‐imidazolium ([Bmim])>1,2‐dimethyl‐3‐butyl ([Bmmim])>1‐butyl‐pyridinium ([Bpy]), which is consistent hydrogen bond donor...
Abstract An intermolecular synergistic catalytic combination of 1,8‐diazabicyclo[5.4.0]undec‐7‐ene (DBU) and a DBU‐derived bromide ionic liquid has been developed for the conversion CO 2 , epoxides, amines under metal‐ solvent‐free conditions. Various 3‐aryl‐2‐oxazolidinones are produced in moderate to excellent yields within short reaction time. NMR spectroscopy DFT calculations demonstrate that DBU as hydrogen bond acceptor donor activate substrates cooperatively by inducing bonds promote...
Homogeneous catalysts generally show higher catalytic activities, while heterogeneous are more easily separated from products. To combine the advantages of and homogeneous has been great interest for many years. Here, we report a kind facilely prepared cross-linked poly(ionic liquid)s (PILs) with swelling property to increase activities catalysts. The ability PILs was greatly affected by cross-linking density chain length substituents on imidazolium, unique prompted nonporous contact...

Acidic poly(ionic liquid)s (PILs) with swelling ability were synthesized by free radical copolymerization of N-vinylimidazolium ionic liquids, divinylbenzene (DVB) and sodium acrylate (NaAA), further acidification sulfuric acid. The acidic PILs was greatly affected cross-linker content chain length 3-alkyl-substituents on imidazolium. Cross-linked network structures could be observed from the cryogenic scanning electron microscopy (cryo-SEM) images swollen in formic state exhibited excellent...

In principle, only very recent...
In this article, a facile and versatile strategy for highly selective detection of Cr(VI) in 100% aqueous solution was developed based on fluorescence inner filter effect (IFE) using hydrophilic ionic chemosensor. the presence Cr(VI), remarkable quenching chemosensor could be observed because strong absorption to both excitation emission light fluorophore (in work, acridine chosen as model fluorophore). By utilizing modified Benesi–Hildebrand equation, not only efficiency IFE quantitatively...
Abstract We have investigated the reactions of cyclic carbonates/trithiocarbonate and aromatic amines in presence a basic ionic liquid, 1‐butyl‐3‐methylimidazolium acetate (BmimOAc), which produced various carbamates/dithiocarbonimidates fairly good to excellent yields. The use BmimOAc as catalyst here not only offers an effective approach synthesis target compounds, but also avoids conventional toxic materials. By means carbonates amines, 3‐aryloxazolidin‐2‐ones,...

Hierarchical porous poly(ionic liquid)s (PILs) with high specific surface area were firstly synthesized via anion exchange. The exchange of bulky salicylate and its dimers/clusters in PILs by other smaller anions increased the fabricated a hierarchical structure. structure prompted degree exposure active sites made heterogeneous PIL catalysts contact substrates sufficiently, enhancing their catalytic activity.
