A series of 2-amino pyridine-3-carbinitrile derivatives incorporated coumarin moiety has developed via multicomponent condensation of 3-acetyl-2H-chromen-2-one, arylaldehydes, malononitrile and ammonium acetate utilizing Brønsted acidic ionic liquid, (4-sulfobutyl)tris(4-sulfophenyl)phosphonium hydrogen sulfate as catalyst under solvent-free conditions. Good yields, short reaction times, straig...

The first bimagnetic ionic liquid based on Fe and TEMPO with cooperative functionalities not only exhibited strong paramagnetic behaviour at room temperature under an applied magnetic field of 5000 Oe but also proved to be an effective catalyst for selective aerobic oxidation of aromatic alcohols under mild and clean conditions.

The two major properties that underpin ionic liquids are tunability and the potential to create task-specific media. Together, these allow surpass roles long held by traditional molecular solvents. However, at elevated temperatures or under prolonged heating, structural components impart such decompose degrade. Dicationic pyridine salts present new opportunities extend functionality high becaus...

Liquid-liquid two-phase systems formed by a hydrophobic ionic liquid and water find several useful ways of application in analytical chemistry. One of the most important properties of such two-phase systems is the mutual solubility of the IL and water. Recent advancements on this subject have been reviewed. The solubility of ionic liquids in water is related to the standard Gibbs energies of th...

A cationic mononitrosyl dinuclear ruthenium complex was prepared by removing one NO ligand of a dicationic dinitrosyl ruthenium complex using NaN3. Reduction and oxidation reactions of the mononitrosyl complex led to the isolation of a neutral nitrosyl-bridged complex and a dicationic mononitrosyl complex, respectively, as expected from the cyclic voltammogram. According to the electron count, ...

Imidocarb [N,N'-bis[3-(4,5-dihydro-1H-imidazol-2-yl)phenyl]urea, C(19)H(20)N(6)O(1), m.w. 348.41] is a symmetrical carbanilide derivative used to treat disease caused by protozoans of the Babesia genus. Imidocarb, however, is also considered capable of suppressing Babesia-specific immune responses, allowing Babesia-positive horses to pass a complement fixation test (CFT) without eliminating the...

systematic studies on the vapor-liquid equilibria (vle) and conductometric properties of aqueous solutions of model surface-active ionic liquid 1-dodecyl-3-methylimidazolium bromide ([c12mim]br) are performed in the absence and presence of a large series of electrolytes in order to achieve a deeper understanding about the molecular mechanism behind the specific salt effect on the aggregation be...

n,n-diethylethanaminium-2-(sulfooxy) ethyl sulfate was synthesized and used as  an efficient, green, and recyclable catalyst and solvent for the nitration of aromatic compounds by nitric acid at 80oc
