Ultrasound-promoted Catalyst-free Synthesis of α-Aminonitriles in 1-Butyl-3-methylimidazolium Bromide ([Bmim]Br) as a Reusable Neutral Ionic Liquid
A catalyst-free one-pot three component methodology for the synthesis of α-aminonitriles under ultrasonic irradiation at room temperature using [Bmim]Br as a neutral reaction medium is described. A broad range of substrates including the aromatic, heteroaromatic and aliphatic aldehydes were condensed with amines (aliphatic and aromatic) and trimethylsilyl cyanide (TMSCN). Using this method, all...
متن کاملTemperature dependent solvation dynamics in an ionic liquid containing microemulsions of 1-butyl-3-methylimidazolium tetrafluoroborate/Triton X–100/cyclohexane
A study of the temperature-dependent solvation dynamics of coumarin-480 in [bmim][BF4]/Triton X-100/cyclohexane microemulsions at three different temperatures (299 K, 308 K and 317 K) is reported. The solvation dynamics of a room temperature ionic liquid in microemulsions becomes faster with increase in temperature. Dynamic light scattering measurements indicate a significant change in size wit...
متن کاملCO2 Capture and Separation Properties in the Ionic Liquid 1-n-Butyl-3-Methylimidazolium Nonafluorobutylsulfonate
Recently, the use of ionic liquids (ILs) for carbon capture and separation processes has gained great interest by many researchers due to the high solubility of CO₂ in ILs. In the present work, solubility measurements of CO₂ in the novel IL 1-n-butyl-3-methylimidazolium nonafluorobutylsulfonate [C₄mim][CF₃CF₂CF₂CF₂SO₃] were performed with a high-pressure view-cell technique in the temperature r...
متن کاملHighly active horseradish peroxidase immobilized in 1-butyl-3-methylimidazolium tetrafluoroborate room-temperature ionic liquid based sol-gel host materials.
Dramatically enhanced activity and excellent thermal stability of horseradish peroxidase were obtained by immobilizing it in a 1-butyl-3-methylimidazolium tetrafluoroborate room-temperature ionic liquid based sol-gel matrix.
متن کاملInfluence of counterions on micellization of tetramethylammonium perfluorononanoic carboxylate in 1-butyl-3-methylimidazolium ionic liquid.
The influence of counterions on micellization of perfluorononanoic carboxylate ammonium salts in water and 1-butyl-3-methylimidazolium tetrafluoroborate ([bmim]BF(4)) solutions was investigated by surface tension and (19)F NMR measurements and freeze-fracture transmission electron microscopy (FF-TEM) observations. Changes in the counterions of the fluorocarbon surfactants have different effects...
