Polyoxometalate and copolymer-functionalized ionic liquid catalyst for esterification*
A new room-temperature ionic liquid (RTIL) consisting of a polyoxometalate (POM) anion and tri-block copolymer (P123)-functionalized imidazolium cation was synthesized and utilized as a halogen-free catalyst for esterification. The catalytic system was a homogeneous solution at the beginning of the reaction, but an emulsion formed during the course of the reaction, and a progressive phase separ...

Application of Acidic Ionic Liquid as a Solvent/Catalyst for Preparation of α-Oximinoketones from β-Dicarbonyl Compounds
The selective nitrosation of β-dicarbonyl compounds with sodium nitrite was carried out under1-methyl-3-carboxymethylimidazolium chloride, prepared from N-methylimidazole andchloroacetic acid, as an acidic ionic liquid. The reaction was found to proceed under relativelymild conditions with excellent conversion and selectivity. The ionic liquid was recycled andreused.
متن کاملDicationic Ionic Liquid as the Recyclable Catalyst for the Synthesis of Quinoxaline Derivatives
An efficient and eco-friendly protocol for the synthesis of quinoxaline derivatives employing a condensation reaction between 1,2-diketone and 1,2-diaminobenzene derivative has been developed. The reaction of 1,2-diketone and 1,2-diaminobenzene derivative was carried out in water at room temperature using 10 mol% of task-specific dicationic ionic liquid as a catalyst. The results show that...
متن کاملPolymer-supported basic ionic liquid as an efficient heterogeneous catalyst system for straightforward synthesis of flavanones
Aromatic aldehydes are efficiently condensed with 2'-hydroxyacetophenone by polymer-supported basic ionic liquid as an excellent heterogeneous catalyst utilizing the Claisen–Schmidt reaction. Microwave irradiation has been employed, providing flavanone in good yield and short reaction time.
